LM3310
Step-up PWM DC/DC Converter with Integrated Op-Amp
and Gate Pulse Modulation Switch
General Description
The LM3310 is a step-up DC/DC converter integrated with
an OperationalAmplifier 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
DSON
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.
