Description
The TLD5095EL is a smart multitopology LED controller with built in protection and diagnostic features. The main
function of this device is to regulate a constant LED current. The constant current regulation is especially beneficial for
LED color accuracy and longer lifetime. The controller concept of the TLD5095EL allows a multi-purpose usage such as
Boost, Buck, Buck-Boost, SEPIC and Flyback configuration with various load current levels by simply adjusting the
external components. The TLD5095EL has a PWM output for dimming a LED load. The diagnostics are communicated
on a status output (pin ST) to indicate a fault condition such as an LED open circuit. The switching frequency is adjustable
in the range of 100 kHz to 500 kHz and can be synchronized to an external clock source. The TLD5095EL features an
enable function reducing the shut-down current consumption to <10 µA. The current mode regulation scheme of this
device provides a stable regulation loop maintained by small external compensation components. The integrated soft-
start feature limits the current peak as well as voltage overshoot at start-up. This IC is suited for use in the harsh
automotive environments and provides protection functions such as output overvoltage protection and
overtemperature shutdown.

Regulator
5 Regulator
5.1 Description
The TLD5095 regulator is suitable for Boost, Buck, Buck-Boost, SEPIC and Flyback configurations. The
constant output current is especially useful for light emitting diode (LED) applications. The regulator function
is implemented by a pulse width modulated (PWM) current mode controller.
The PWM current mode controller uses the peak current through the external power switch and error in the
output current to determine the appropriate pulse width duty cycle (on time) for constant output current. The
current mode controller it provides a PWM signal to an internal gate driver which then outputs the same PWM
signal to external n-channel enhancement mode metal oxide field effect transistor (MOSFET) power switch.
The current mode controller also has built-in slope compensation to prevent sub-harmonic oscillations which
is a characteristic of current mode controllers operating at high duty cycles (>50% duty).
An additional built-in feature is an integrated soft start that limits the current through the inductor and
external power switch during initialization. The soft start function gradually increases the inductor and switch
current over 1 ms (typical) to minimize potential overvoltage at the output.

Oscillator and Synchronisation
6Oscillator and Synchronisation
Description
R_OSC vs. switching frequency
The internal oscillator is used to determine the switching frequency of the multitopology regulator. The
switching frequency can be selected from 100 kHz to 500 kHz with an external resistor to GND. To set the
switching frequency with an external resistor the following formula can be applied.
(6.1)
In addition, the oscillator is capable of changing from the frequency set by the external resistor to a synchronized
frequency from an external clock source. If an external clock source is provided on the pin FREQ/SYNC, then the
internal oscillator synchronizes to this external clock frequency and the multitopology regulator switches at the
synchronized frequency. The synchronization frequency capture range is 250 kHz to 500 kHz.

Enable and Dimming Function
7Enable and Dimming Function
Description
The enable function powers on or off the device. A valid logic low signal on enable pin EN/PWMI powers off the
device and current consumption is less than 10 µA. A valid logic high enable signal on enable pin EN/PWMI
powers on the device. The enable function features an integrated pull down resistor which ensures that the IC
is shut down and the power switch is off in case the enable pin EN is left open.
In addition to the enable function described above, the EN/PWMI pin detects a pulse width modulated (PWM)
input signal that is fed through to an internal gate driver. The internal gate driver outputs the same PWM signal
on the PWMO pin to an external n-channel enhancement mode MOSFET for PWM dimming an LED load. PWM
dimming an LED is a commonly practiced dimming method to prevent color shift in an LED light source.
Moreover the PWM output function may also be used for to drive other types of loads besides LED.
The enable and PWM input function share the same pin. Therefore a valid logic low signal at the EN/PWMI pin
needs to differentiate between an enable power off signal or an PWM low signal. The device differentiates
between an enable off command and PWM dimming signal by requiring the signal at the EN/PWMI pin to stay
low for a minimum of 8 ms.

Linear Regulator
8Linear Regulator
Description
The internal linear voltage regulator supplies the internal gate drivers with a typical voltage of 5 V and current
up to ILIM,min (parameter 8.2.2). An external output capacitor with ESR lower than RIVCC,ESR (parameter
8.2.5) is required on pin IVCC for stability and buffering transient load currents. During normal operation the
external MOSFET switches will draw transient currents from the linear regulator and its output capacitor.
Proper sizing of the output capacitor must be considered to supply sufficient peak current to the gate of the
external MOSFET switches.
Integrated Undervoltage Protection for the External Switching MOSFET
An integrated undervoltage reset threshold circuit monitors the linear regulator output voltage (VIVCC) and resets
the device in case the output voltage falls below the IVCC undervoltage reset switch OFF threshold (VIVCC,RTH,d).
The undervoltage reset threshold for the IVCC pin helps to protect the external switches from excessive power
dissipation by ensuring the gate drive voltage is sufficient to enhance the gate of an external logic level n-channel
MOSFET.

Protection and Diagnostic Functions
9 Protection and Diagnostic Functions
9.1 Description
The TLD5095EL has integrated circuits to diagnose and protect against output overvoltage, open load, open
feedback and overtemperature faults. In case any of the four fault conditions occur the Status output ST will output
an active logic low signal to communicate that a fault has occurred. During an overvoltage or open load condition
the gate driver outputs SWO and PWMO will turn off. Figure 9-3 illustrates the various open load and open
feedback conditions. In the event of an overtemperature condition (Figure 9-6) the integrated thermal shutdown
function turns off the gate drivers and internal linear voltage regulator. The typical junction shutdown temperature
is 175°C. After cooling down the IC will automatically restart operation. Thermal shutdown is an integrated
protection function designed to prevent immediate IC destruction and is not intended for continuous use in normal
operation.
