SY50133充电器IC 全新原装矽力杰一级代理5V SOP8 芯片
税前: ¥1.00
General Description
SY50133 is a single stage Flyback controller targeting at Constant Current/Constant
Voltage (CC/CV) applications.
It integrates a 600V MOSFET to decrease physical volume. Both the output current and
voltage are sensed by primary side signal process. SY50133 operates quasi-resonant
mode and adaptive PWM/PFM control for highest average efficiency. In addition,
SY50133 has cable compensation to regulate the output voltage for better load
regulation at cable terminal.
Features
Very tight PSR CC/CV regulation over entire operating range
QR-mode operation for high efficiency
PWM/PFM control for higher average efficiency
Internal CC/CV loop compensation
The self-adaption compensation for better stability
Fast dynamic load transient response
Cable compensation for better load regulation
Low start up current: 4µA Max
Reliable protections for OVP, SCP, OTP
Reliable protections for safety requirement
Integrated 600V MOSFET
Compact package: SO8
Applications
AC/DC adapters
Battery Chargers
