1.25MHz, 2A, High Efficiency PWM Step-Down DC/DC Converter - AN6032

AN6032 is a high efficiency step-down DC/DC converter operated with the current mode and the constant frequency. The internal switch and synchronous rectifier are integrated for high efficiency. AN6032 can supply 2A of load current from 2.7V to 5.5V supply voltage. The switching frequency is set at 1.25MHz, allowing the use of small surface mount inductors and capacitors. It can run 100% duty cycle for low dropout application. AN6032 is available in a DFN3X3-10 package.
