Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MAX77646ANP provides power solutions for low-power applications where size and efficiency are critical. The IC integrates a single inductor Multiple Output (SIMO) buck/boost regulator to provide three independently programmable power rails through a single inductor, minimizing the overall solution size. The 150mA LDO provides ripple suppression for audio and other noise sensitive applications. Ldos can also be configured as load switches to manage power consumption by disconnecting external modules when they are not needed.

Features

Input range: 1.8V to 3.3V

Highly integrated

3 output, single inductance Multiple output (SIMO) buck - boost regulator

All SIMO channels support a wide output voltage range from 0.5V to 5.1V

One 150mA LDO

The value is 100mA in LSW mode

2 GPIOs (MAX77647)

Watchdog Timer (MAX77647)

Ultra-low power SIMO

Working current: 1.3μA (3 SIMO channels)

Turn-off current: 0.1μA

Efficiency in step-down mode only: 85% (VIN = 2.4V, VOUT = 0.8V, 10mA, IPK = 0.5A)

Efficiency in step-boost mode: 86% (VIN = 2.4V, VOUT = 1.8V, 10mA, IPK = 0.5A)

When VOUT = 1.8V, the output ripple is less than 20mVpp

Automatic conversion from low power mode to normal power mode

Flexible and configurable

Ultra configurable resistive programmable output voltage (MAX77646)

I2C Programmable output voltage (MAX77647)

subsize

5mm2 wafer-level Package (WLP)

20 pin, 0.5mm pitch, 5 x 4 array package

• 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.
