Product Overview
The MAX1515ETG+ is a low voltage, internal switch, step-down/DDR regulator in 24 pin TQFN package. The MAX1515 constant-off-time, pulse-width-modulated (PWM) source/sink step-down DC to DC converter used in low voltage active-termination power rails or chipset power supplies. 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 40mohm NMOS power switches easily source and sink continuous load currents up to 3A. It produces an adjustable output from +0.5V to +2.7V and achieves efficiencies as high as 95%. The MAX1515 can be configured as a DDR regulator, producing an output that is exactly half the memory supply rail. The input of the power stage can be taken from the memory supply rail itself, resulting in an efficient power supply that returns the energy to the rail from which it was sourced.
