Portable DLP Pico Projector Reference Design with 5-20V Input Voltage 3-Cell Battery Charger

PMP40069

Overview

The PMP40069 reference design is for portable DLP Pico projectors. It also comes with a 3-cell battery charger. The battery powers the projector when the adapter is unavailable. This solution implements the DLPA3000 PMIC/LED driver, DLPC3438 display controller and SMBus battery buck/boost charge controller BQ25700A. DLPA3000 PMIC is a fully integrated dedicated PMIC/LED driver that meets various system analog power requirements and can drive 0 ~ 6A RGB LEDs. The buck/boost charger is compatible with 5/9/12/15/20V output adapters. The charger is highly efficient and can provide 3A charging current for 3 batteries.
