2A, 2MHz, High Efficiency PWM Step-Down DC/DC Converter - AN6072

The AN6072 is a high efficiency synchronous, step-down DC/DC converter. Its input voltage range is from 2.7V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 2A of output current. The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency can be varied from 300kHz to 2MHz by changing an external resistor. Current mode operation with external compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The AN6072 operates in forced continuous PWM Mode, which minimizes ripple voltage and reduces the noise and RF interference.
