Synthetic power supply

Overview

1. Product introduction
: A portable adjustable power supply that can be powered by batteries and PD. The two power supplies can be operated independently. When two power supplies exist at the same time, both can bear the output at the same time, and the power can be expanded to 100w+.

2. Application scenarios
1. Outdoor maintenance occasions
2. Desktop adjustable power supply

3. Product overview
This module uses STM32 closed-loop design, PD input (8V to 20V DC input), high current output (6A), and wide adjustable voltage output power supply (1V-36V adjustable output) design, with constant voltage function, 6A output current driving capability, high efficiency, and low ripple.

4. Product parameters
Electrical parameters:
1. Input type: 18650 two sections, 8-20v DC input (PD20V recommended);
2. 1V-36V adjustable output;
3. Maximum 6A current output capability;
4. Maximum output power 120W;
5. 2w standby;
6. Working frequency: 34KHz;
7. Low ripple, maximum no-load 50mv, full load maximum 100mv;

This design contains two PCBs
