LM2618 - Synchronous PWM & PFM Programmable DC-DC Converter

Download the LM2618 datasheet PDF. This datasheet also covers the LM2 variant, as both devices belong to the same synchronous pwm & pfm programmable dc-dc converter family and are provided as variant models within a single manufacturer datasheet.

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.

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.

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 Converter 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. Pin programmable output voltages of 1.80V, 1.83V, 1.87V or 1.92V allow adjustment for MPU voltage options without board redesign or external feedback resistors. Internal synchronous rectification provides high efficiency in both PWM and PFM operation.
