General Description
The RT9758 is a high efficiency and high charge current
charger for high voltage application. The efficiency is up
to 98.1 when VOUT = 10V, IOUT = 2A, switching
frequency = 500kHz, dual phase with VBUS input in cap
divider mode. The RT9758 maximum charge current is
up to 5A. The device integrates cap divider topology
(DIV2 mode), direct charge topology (Bypass mode), an
input reverse blocking NFET, a dual-phase charge
pump core, the EN pin control and 9-way protection. In
present mode (EN = H), the host can still order the
command by I2C serial interface.
Features
⚫ Integrated Bidirectional Bypass Mode and Cap
Divider Mode (DIV2 Mode)
