1.5MHz, 1.3A, High Efficiency PWM Step-Down DC/DC - AN6008

AN6008 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. External Schottky diodes are not required. The supply current is only 200μA during operation and drops to less than 1μA in shutdown. AN6008 can supply 1.3A of load current from 2.5V to 5.5V supply voltage. The output voltage can be regulated as low as 0.6V. The switching frequency is set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. It can run 100% duty cycle for low dropout application. AN6008 is available in a low profile SOT23-5 package.
