Texas Instruments bq25300EVM/bq25303JEVM Evaluation Module (EVM)

Texas Instruments bq25300EVM/bq25303JEVM Evaluation Module (EVM) is used to evaluate the bq2530x devices. The bq2530x is a highly integrated 3A standalone 1-cell, 17V, 1.2MHz synchronous switch-mode buck battery charger. The evaluation module is a complete charger module for evaluating an integrated, standalone, synchronous buck battery charger using the Texas Instruments bq25300, bq25302, or bq25303J.

Features

High efficiency 1.2MHz synchronous switch-mode buck charger
Single input to support USB input adapters

Input voltage dynamic power management (VINDPM)
1µA low battery leakage current with adapter unplugged
Supports 300mA to 3A charge current
