Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC7851EUHH device is a four-channel output, multi-phase synchronous step-down type switching regulator controller that employs a constant frequency voltage mode architecture. When connected in parallel with its internal current-sharing loop, the LTC7851EUHH can maintain excellent current balance between channels. Non-destructive DCR or a low-value RSENSE is used for output current detection. For high phase bit operations, multiple LTC7851 devices can be used.

Besides. The LTC7851EUHH mainly has the following features:

It operates using a Power Block, DrMOS or an external gate driver and MOSFET

Voltage mode control with accurate current equalization function

±0.75% 0.6V voltage reference

Four-channel differential output voltage detection amplifier

Multiphase ability

Phase-locked fixed frequency: 250kHz to 2.25MHz

Lossless current detection using inductor DCR, or precise current detection using detection resistors or DrMOS with integrated current-sharing function circuits

VCC range: 3V to 5.5V

VOUT range: 0.6V to VCC - 0.5V

Good power supply output voltage monitor

Output voltage tracking capability and soft start

It adopts a 58-pin 5mm x 9mm QFN package

Application scenarios

The LTC7851EUHH is widely used in scenarios that require high-power and high-efficiency power management, such as:

High-current distributed power supply system

DSP, FPGA and ASIC power supplies

Data communication, telecommunications and computing systems

• 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.
