Description

The SLM6635 is a 3A single cell Li-ion battery charger applied for 5V adapters. It utilizes 0.8MHz synchronous buck converter topology to reduce power dissipation and therefore reaches a high efficiency up to 92%.

The SLM6635 includes complete charge termination circuitry, automatic recharge, and a ±1% 4.35V float voltage. It also has other features include output short-circuit protection, battery temperature nitor, overheating protection, and no blocking diode is required.

The SLM6635 is available in ESOP8 package with heat sink. Its few external component count makes the SLM6635 a high-efficient battery charger ideally suited for portable applications.
