Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The two-phase synchronous boost controller LTC7806JUFDM drives two N-channel power MOSFET stages out of phase. Its constant frequency current mode architecture supports phase-locked switching frequencies up to 3MHz. High-frequency two-phase operation reduces input and output capacitance requirements and allows the use of smaller inductors compared to single-phase equivalent circuits. Synchronous rectification simplifies high-power boost applications by increasing efficiency and reducing power consumption and heat dissipation requirements.

Features

2-phase operation reduces the required input and output capacitance as well as power supply induced noise

Synchronous operation for maximum efficiency and reduced heat dissipation

Wide input voltage range: 4.5V to 40V after start-up, and can operate as low as 1V

Output voltage up to 40V

Low working static current: 18μA

PassThru™ operation: Synchronize 100% duty cycle capacity of the MOSFET

RSENSE or inductor DCR current detection

Spread spectrum operation

Programmable fixed frequency (100 kHz to 3 MHz)

Phase-locked frequency (100 kHz to 3 MHz)

For light loads, choose continuous, pulse jump or low ripple burst mode ® operation

Input current monitor output

The internal LDO supplies power to the gate drive via VBIAS or EXTVCC

Low turn-off IQ: 1.5μA

Side wettable 28 pin 4 mm x 5 mm QFN package

Passed AEC-Q100 Automotive application certification

• 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.
