GENERAL DESCRIPTION

The ADPL13602 is a high-efficiency, synchronous stepdown

DC-DC converter with integrated MOSFETs

operating over an input-voltage range of 3.5V to 36V. It

can deliver up to 2.4A current. Output voltage is

programmable from 1V up to 90 of VIN. Built-in

compensation across the output-voltage range

eliminates the need for external compensation

components.

The ADPL13602 features a peak-current-mode control

architecture. The ADPL13602 can be operated in forced

pulse-width modulation (PWM) or discontinuousconduction

mode (DCM) to enable high efficiency under

full-load and light-load conditions. The ADPL13602

offers a low minimum on-time that allows high

switching frequencies and a smaller solution size.

The feedback-voltage regulation accuracy over -40°C to

+125°C is ±1.5. The device is available in a 16-pin (3mm

x 3mm) TQFN-EP package. Simulation models are available.
