LM2700 Datasheet Step-up Pwm DC/dc Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM2700 600kHz/1.25MHz, 2.5A, Step-up PWM DC/DC Converter October 2001 LM2700 600kHz/1.25MHz, 2.

General Description

The LM2700 is a step-up DC/DC converter with a 3.6A, 80mΩ internal switch and pin selectable operating frequency.

With the ability to produce 500mA at 8V from a single Lithium Ion battery, the LM2700 is an ideal part for biasing LCD displays.

The LM2700 can be operated at switching frequencies of 600kHz and 1.25MHz allowing for easy filtering and low noise.

Key Features

  • continuous switching at light loads and operates with a switching quiescent current of 2.0mA at 600kHz and 3.0mA at 1.25MHz. The LM2700 is available in a low profile 14-lead TSSOP package or a 14-lead LLP package. n n n n n Input undervoltage protection Adjustable output voltage up to 17.5V 600kHz/1.25MHz pin selectable frequency operation Over temperature protection Small 14-Lead TSSOP or LLP package.
