OB2372
DESCRIPTION
FEATURES
OB2372 is an excellent primary side regulation
- Primary-side sensing and regulation operates controller with CC/CV operation for medium level in CCM/QR mode without TL431 and power AC/DC charger and adapter applications. opto-coupler
The device directly drives a power MOSFET and
- High precision constant voltage and current operates in CCM/QR mode to provide high regulation at universal AC input efficiency along with several functions of built-in
- Fixed frequency (65k Hz) CCM mode protections. It removes the need for secondary operation with low line voltage at full load feedback circuitry to lower the total bill of material
- Quasi-resonant operation for high efficiency in cost. Proprietary Constant Voltage (CV) and high line voltage
Constant Current (CC) control is integrated as
- Good dynamic response shown in the figure below.
- Programmable CV and CC regulation
In CV control, the controller changes the mode of
- Built-in primary winding...
