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.
