Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC7805JUFDM is a high performance, dual output, step-down synchronous DC/DC switching regulator controller that drives the full N-channel power MOSFET stage. The constant-frequency current-mode architecture allows for phase-lockable switching frequencies up to 3 MHz, and the LTC7805 operates over a wide input supply range of 4.5V to 40V. Power loss and supply noise are minimised by operating the two control output stages in heterodyne.

Features

Wide input voltage range: 4.5V to 40V

Wide output voltage range: 0.8V to 40V

Low operating IQ

14 μA (14 V to 3.3 V, channel 1 on)

PassThru™/100% duty cycle capability

Spread spectrum operation

RSENSE or DCR current sense

In-phase controller reduces required input capacitance and supply-induced inductive noise

Programmable fixed frequency (100 kHz to 3 MHz)

Phase-lockable frequency (100 kHz to 3 MHz)

Selectable continuous, pulse-skipping, or low-ripple Burst Mode® operation at light loads

Power supply normal output voltage monitor

Internal LDO feeds gate drive through VIN or EXTVCC

Low shutdown IQ: 1.5μA

Side-wettable 28-pin 4 mm × 5 mm QFN package

Certified to AEC-Q100 for automotive applications

• 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.
