APW7213/4 1.4MHz, High-Efficiency, Step-Up Converter for 2 to 8 White LEDs Features General Description * Wide Input Voltage from 2.5V to 6V * Fixed 1.4MHz Switching Frequency The APW7213/4 is a current-mode and fixed frequency boost converter with an integrated N-FET and Schottky * High Efficiency up to 80% * PWM Brightness Control with Wide Frequency diode to drive up to 8 white LEDs in series. The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and low feedback voltage reduce power loss and achieve Range of 100Hz to 200kHz * Build-In Schottky Diode * Open-LED Protection * Under-Voltage Lockout Protection * Over-Temperature Protection * <1A Quiescent Current During Shutdown * SOT-23-6, TSOT-23-6A, and TDFN2x2-8 Packages * Halogen and Lead Free Available high efficiency. Fast switching frequency (1.4MHz typical) allows using small-size inductor and both of input and output capacitors. An over-voltage protection function, which monitors the output voltage via VOUT pin, stops switching of the IC if the VOUT voltage exceeds the overvoltage threshold. An internal soft-start circuit eliminates the inrush current during start-up. The APW7213/4 also integrates under-voltage lockout, (RoHS Compliant) over-temperature protection, and current-limit circuits to protect the IC in abnormal conditions.The APW7213/4 is Applications available in a SOT-23-6, TSOT-23-6A, and TDFN2x2-8 packages. * White LED Display Backlighting * Cell Phone and Smart Phone Simplified Application Circuit * PND * Digital Camera L1 22H VIN C1 2.2F Pin Configuration VIN VOUT (Option) LX C2 0.22F Up to 8 WLEDs GND VOUT APW7213/4 APW7213/4 OFF ON APW7213/4 EN FB R1 LX 1 GND 2 FB 3 6 VIN 5 VOUT 4 EN GND VIN VOUT EN SOT-23-6/TSOT-23-6A (Top View) 1 2 3 4 8 7 GND 6 5 LX NC FB GND APW7213: VOUT OVP with hysteresis to re-start.

A.1 - Mar., 2011 9 www.anpec.com.tw APW7213/4 Application Information The peak inductor current is calculated as the following equation: 1 V (VOUT - VIN ) IPEAK = IIN(MAX ) + IN 2 VOUT L FSW Input Capacitor Selection The input capacitor (CIN) reduces the ripple of the input current drawn from the input supply and reduces noise injection into the IC. The reflected ripple voltage will be smaller when an input capacitor with larger capacitance is used. For reliable operation, it is recommended to VIN select the capacitor with maximum voltage rating at least 1.2 times of the maximum input voltage. The capacitors IL IIN LX N-FET CIN IOUT D1 VOUT ESR ISW should be placed close to the VIN and GND. COUT Inductor Selection IL Selecting an inductor with low dc resistance reduces conduction losses and achieves high efficiency. The efficiency ILIM is moderated whilst using small chip inductor which op- IPEAK erates with higher inductor core losses. Therefore, it is IL necessary to take further consideration while choosing IIN an adequate inductor. Mainly, the inductor value determines the inductor ripple current: larger inductor value ISW results in smaller inductor ripple current and lower conduction losses of the converter. However, larger inductor value generates slower load transient response. A reasonable design rule is to set the ripple current, IL, to be 30% to 50% of the maximum average inductor current, IL(AVG). The inductor value can be obtained as below, V L IN VOUT ID 2 VOUT - VIN x x F xI IL SW OUT (MAX ) IL (AVG ) IOUT Output Capacitor Selection where The current-mode control scheme of the APW7213/4 al- VIN = input voltage lows the usage of tiny ceramic capacitors.

The output ripple is the sum of the voltages across the ESR and the ideal = Efficiency IL /IL(AVG) = inductor ripple current/average current output capacitor.
