Describe
LED driver IC 1 output DC DC controller SEPIC, step-down, step-up analog, PWM dimming 28QFN

Product Description

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.

FAQ

  • 1.Is the inventory and price seen on the platform accurate?

    A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

  • 2.Are all our products genuine?

    A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

  • 3.Can you provide the qualification certificate of the original factory or agent?

    A: at present, our self-employed brands TI,ST,ADI,NXP,LATTICE,CYPRESS,INFINEON,XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

  • 4.Can I make an inquiry through the company's website?

    A: You can inquire through the website, or by phone and email.

  • 5.When can I deliver the goods after placing an order? How long will it take to get there?

    A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

  • 6.Can the company issue an invoice?

    A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
