LT3932EUFD-1描述

The LT®3932 , featuring the Silent Switcher®architecture
to minimize EMI/EMC emissions, utilizes fixed-frequency,
peak current control and provides PWM dimming for a
string of LEDs. The LED current is programmed by an analog
voltage or the duty cycle of pulses at the CTRL pin. An
output voltage limit can be set with a resistor divider to
the FB pin.
The switching frequency is programmable from 200kHz to
2MHz by an external resistor at the RT pin or by an external
clock at the SYNC/SPRD pin. With the optional spread
spectrum frequency modulation enabled, the frequency
varies from 100% to 125% to reduce EMI. The LT3932
also includes a driver for an external, high side PMOS for
PWM dimming and an internal PWM signal generator for
analog control of PWM dimming when an external signal is
not available. The LT3932-1 permits higher dimming ratios.
Additional features include an LED current monitor, an
accurate EN/UVLO pin threshold, open-drain fault reporting
for open-circuit and short-circuit load conditions, and
thermal shutdown.
