Intersil EL7536 Step-Down Regulator Datasheet
The EL7536 is a synchronous, integrated FET 1 A step‑down regulator that operates from 2.5 V to 5.5 V input and provides an adjustable output from 0.8 V up to the input voltage. It features an internally‑compensated controller, PWM mode operation at a typical 1.4 MHz switching frequency, and includes protection functions such as short‑circuit, over‑temperature, and a shutdown current of less than 1 pA. The device is offered in a 10‑lead MSOP package with a footprint of less than 0.15 in², suitable for compact PCB designs.
Designed for portable electronics such as PDAs, pocket PCs, barcode readers, and Li‑ion battery‑powered devices, the EL7536 requires only two ceramic capacitors and an inductor to form a complete DC‑DC converter. The datasheet provides detailed pin descriptions, performance curves, application guidelines, and component selection recommendations to aid designers in implementing the regulator in their circuits.
