MAX1515 datasheet

Description :

The MAX1515 constant-off-time, pulse-width-modulated(PWM) source/sink step-down DC-DC converter is optimized for use in low-voltage active-termination power rails or chipset power supplies in notebook and sub notebook computers. This device features dual internal n-channel MOSFET power switches for high efficiency and reduced component count. External Schottky diodes are not required. An integrated boost switch
eliminates the need for an external boost diode. The internal 40mΩNMOS power switches easily source and sink continuous load currents up to 3A. The MAX1515 produces an adjustable output from +0.5V to +2.7V and achieves efficiencies as high as 95%.
