NOT RECOMMENDED FOR NEW DESIGNS SEE EL7532 EL7562 Monolithic 2Amp DC-DC Step-Down Regulator DATASHEET FN7295 Rev 1.00 May 1, 2006 The EL7562 is an integrated, synchronous step-down regulator with output voltage adjustable from 1.0V to 3.8V.

It is capable of delivering 2A continuous current at up to 95% efficiency.

The EL7562 operates at a constant frequency pulse width modulation (PWM) mode, making external synchronization possible.

Patented on-chip resistorless current sensing enables current
