Description

The PMP40069 is a reference design for portable DLP pico projectors  It also has a 3 cell battery charger.  The battery will provide the power to the projector when the adapter isn't available . The solution implements  DLPA3000 PMIC/LED driver, DLPC3438 display controller and SMBus battery buck-boost charge controller BQ25700A. The DLPA3000 PMIC is a fully integrated dedicated PMIC/LED driver providing all system analog power requirements and can drive 0~6 amp RGB LEDs. The buck-boost charger is compatible with 5/9/12/15/20V output adapters. The charger has high efficiency and provides 3A charge current to a 3 cell battery.

Features
  • Dedicated PMIC/LED driver providing all system analog power requirements
  • 6A maximum LED current
  • 5/9/12/15/20V input charger for 3 cell battery
  • 3A maximum charge current
  • Fully tested
