LM3310

Step-up PWM DC/DC Converter with Integrated Op-Amp

and Gate Pulse Modulation Switch

General Description

Features

n Boost converter with a 2A, 0.18Ω switch

n Boost output voltage adjustable up to 20V

n Operating voltage range of 2.5V to 7V

n 660kHz/1.28MHz pin selectable switching frequency

n Adjustable soft-start function

The LM3310 is a step-up DC/DC converter integrated with

an Operational Amplifier and a gate pulse modulation switch.

The boost (step-up) converter is used to generate an adjust-

able output voltage and features a low R_DSONinternal switch

for maximum efficiency. The operating frequency is select-

able between 660kHz and 1.28MHz allowing for the use of

small external components. An external soft-start pin en-

ables the user to tailor the soft-start time to a specific appli-

cation and limit the inrush current. The Op-Amp is capable of

sourcing/sinking 135mA of current (typical). The gate pulse

modulation switch can operate with a VGH voltage of 5V to

30V. The LM3310 is available in a low profile 24-lead LLP

package.

n Input undervoltage protection

n Over temperature protection

n Integrated Op-Amp

n Integrated gate pulse modulation (GPM) switch

n 24-Lead LLP package

Applications

n TFT Bias Supplies

n Portable Applications
