Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX25203DATJA is an automotive two-phase synchronous boost controller with programmable gate drive and I2C interface ‌. It can maintain regulation during cold start or start-stop operations, with a minimum input voltage of up to 1.8V. The MAX25203DATJA can start within an input voltage range of 4.5V to 42V and continue to operate up to 1.8V after startup. The output voltage is adjustable from 12V to 65V with ±1.5% output voltage accuracy ‌.

Features

The MAX25203DATJA has the following main features:

Meet the strict OEM module power consumption and performance specifications

The output voltage accuracy on the FB side is ±1.5%

The output voltage can be adjusted between 12V and 65V (70V, absolute maximum value).

The power supply cut-off current is 5μA

High efficiency and current sharing

The efficiency is over 98%

A one-time programmable (OTP) gate drive voltage ranging from 6.5V to 10V enables users to optimize external MOSFETs and enhance efficiency

The current sharing accuracy among each phase is ±5%, which can improve the system efficiency

Programmable current limit blanking can handle high-peak loads without the need for overly large inductors

The EMI suppression function can effectively reduce interference to sensitive radio frequency bands without compromising the wide input voltage range

Spread spectrum option

Real-time frequency synchronization input

The programmable frequency of the resistor ranges from 220kHz to 2.1MHz

Synchronous output provides a 90° out-of-phase clock for four-phase operation

Integrated and heat-resistant performance enhanced packaging saves circuit board space and cost

Current mode controller with forced continuous and jump modes

The 32-pin TQFN-EP package is wettable on the side

Protection functions and I2C diagnosis can enhance the reliability of the system

Operate under-voltage locking

Short-circuit protection with True ShutdownTM

Under-voltage locking of the power supply is achieved through I2C

Monitor the temperature of the die through I2C

Monitor the currents of each phase through I2C

Application scenarios

The MAX25203DATJA is widely used in automotive infotainment systems, automotive audio amplifiers and other applications. It can remain in the adjusted state during cold crank or start-stop operation until the battery input is 1.8V. In addition, it can be used to generate voltage display backlight and Class D audio amplifiers ‌.

• 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.
