ISL6406MR, ISL6406MV
Enhanced Product (EP) Single
Synchronous Buck Pulse-Width
Modulation (PWM) Controller
The ISL6406MREP and ISL6406MVEP are adjustable
frequency, synchronous buck switching regulators optimized
for generating lower voltages for distributed DC/DC
architectures. Both devices feature an adjustable output
voltage.
Designed to drive N-Channel MOSFETs in a synchronous
buck topology, the ISL6406MREP and ISL6406MVEP
integrate the control, output adjustment and protection
functions into a single package.
The ISL6406MREP and ISL6406MVEP provide simple,
single feedback loop, voltage-mode control with fast
transient response. The output voltage can be precisely
regulated to as low as 0.8V. The error amplifier features a
15MHz gain-bandwidth product and 6V/μs slew rate which
enables high converter bandwidth for fast transient
performance.
Protection from overcurrent conditions is provided by
monitoring the rDS(ON) of the upper MOSFET to inhibit PWM
operation appropriate ly. Th is approach simplifies the
implementation and improves efficiency by eliminating the
need for a current sense resistor.
The wide programmable switching frequency range of
100kHz to 700kHz allows the use of small surface mount
inductors and capacitors. The device also provides external
frequency synchronization making it an ideal choice for
DC/DC converter applications.

The specifications for an Enhanced Product (EP) device are
defined in a Vendor Item Drawing (VID), which is controlled
