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

Required Equipment

  • Power Supply #1 (PS1)
    • A power supply capable of supplying 5V at 3A is required
    • While this part can handle larger voltage and current, it is not necessary for this procedure
  • Power Supply #2 (PS2)
    • A power supply capable of supplying 5V at 1A is required
  • Load #1
    • 4-Quadrant Supply, Constant Voltage < 4.5V
    • A “Kepco” Load, BOP, 20-5M, DC 0 to ±20V, 0 to ±5A (or higher)
    • Alternative Option: A 0–20V/0–5A, > 30W DC electronic load set in a constant voltage loading mode
  • Meters
    • (4x) “Fluke 75” multimeters (equivalent or better)
