I am the king of evaluation boards - embedded power management evaluation boards

Overview

This evaluation board uses the Injoinic chip IP5306 to provide a 5V boost function for power on/off. The IP2312 provides buck charging for high-efficiency charging. The IP3005A provides multiple protections for lithium battery charging and discharging.

This entire evaluation board uses Injoinic chips and has already been implemented in my products. The IP5306 can be used for one-button power on/off, and two output voltages can be customized.
When the IP2312 is charging the battery, the IP5306 will not restart, unlike some power banks that disconnect the output when charging or unplugging the charger.
The IP3005A is essential for protecting the lithium battery from overcharging, over-discharging, and overcurrent.

All three chips are priced under 1.5 RMB each, with free shipping!
