The LT3762EUFD is a synchronous DC/DC controller, suitable for use as a constant current source and constant voltage regulator. It adopts a programmable internal PWM dimming signal generator and a synchronous gate driver. The following are its core features and parameters:
3000:1 external PWM dimming
250:1 internal PWM dimming
Wide VIN operating range: 2.5V to 38.5V
Synchronous boost output voltage up to 60V
Spread spectrum modulation suitable for lower EMI
PMOS switch driver suitable for PWM and output disconnection functions
Constant current (±3.5%) regulation
Constant pressure (±2%) regulation
Rail-to-rail LED current sensing: 0V to 60V
Programmable VIN undervoltage lock
Simulated dimming is carried out through two control pins
Operating frequency: 100 KHZ to 1MHz
Implement programmable LED open-circuit protection using OPENLED markers
Short-circuit protection and SHORTLED marking
Drive the LED in boost, SEPIC, buck mode or boost/buck mode configuration
28-pin QFN (4mm × 5mm) bare pad package
The LT3762EUFD is suitable for driving high-current leds with high efficiency and low power loss. Rail-to-rail switch current sensing supports both synchronous boost topology and asynchronous topology (such as SEPIC). The voltage feedback pin serves as the input for multiple LED protection functions while allowing the converter to operate as a constant voltage source.
In addition The LT3762EUFD also includes an integrated DC/DC converter to efficiently generate a regulated 7.5V power supply for the N-channel MOSFET gate driver. The PWM pin controls the PWMTG to drive the P-channel MOSFET, thereby achieving a high PWM dimming range (3000:1) and providing LED overcurrent protection and short-circuit protection boost capabilities.
