RT9758規(guī)格書詳情
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

= 2A, Switching Frequency = 500kHz and Dual
Phase with VBUS Input in DIV2 Mode
? 300kHz to 1.5MHz Variable Switching
Frequency Stay Out of Audio Band
? Spread Spectrum Technology for EMI
Reduction
? Adjustable Single-Phase or Dual-Phase for
DIV2 Mode
? Programmable Pre-Charge Current and Pre-
Charge Timing for Charge Soft-Start

Application
? Operation Mode Transfer Automatically between
Bypass Mode and DIV2 Mode (AT_Function)
? I2C is Available when Device in Present Mode
? 3-Error Charge Pump Switch Protection
? VBUS Voltage Too Low Error Protection before
Switch (VBUS_LOW_ERR)
? CFLY Short Error Protection Before Switch
(CFLY_DIAG)
? Converter Over-Current Protection (CON_OCP)
? 6-Way System Protection
