General Description

The LM2618 step-down DC-DC converter is optimized for powering low voltage circuits from a single Lithium-Ion cell.

It provides up to 400mA (300mA for B grade), over an input voltage range of 2.8V to 5.5V.

Overview

LM2618 400mA Sub-miniature, High Efficiency, Synchronous PWM & PFM Programmable DC-DC Converter September 2002 LM2618 400mA Sub-miniature, High Efficiency, Synchronous PWM & PFM Programmable DC-DC.

Key Features

  • include soft start and current overload protection. The LM2618 is available in a 10 pin micro SMD packge. This package uses National’s wafer level chip-scale micro SMD technology and offers the smallest possible size. Only three small external surface-mount components, an inductor and two ceramic capacitors are required. Key Specifications n Operates from a single LiION cell (2.8V to 5.5V) n Internal synchronous rectification provides high efficiency in both PWM and PFM n Pin programmable outpu.
