1.2MHz,30V/1.4A High Performance, Boost Converter

General Description

The LP3316 is a 1.2MHz PWM boost switching

regulator designed for constant-voltage boost

applications. The LP3316 can drive a string of up to

30V. The LP3316 implements a constant frequency

1.2MHz PWM control scheme. The high frequency

PWM operation also saves board space by reducing

external component sizes. To improve efficiency, the

feedback voltage is set to 1250 mV, which reduces

the power dissipation in the voltage setting resistor.

Highly integration and internal compensation

network minimizes as 5 external component counts.

Optimized operation frequency can meet the

requirement of small LC filters value and low

operation current with high efficiency.
