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, 0.18switch  
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 RDSON internal 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
