OB2223F
High Precision Low Cost MCM Power Switch
GENERAL DESCRIPTION
OB2223F is a high performance, high precision
and low cost PWM Power switch for non-isolated
buck and flyback application. It combines a
dedicated current mode PWM controller (with a
high voltage power MOSFET with SOP8/DIP7
package) and built-in error amplifier optimized for
good overshoot and dynamic response for low
cost and component count. With precise inner
resistor divider, precise reference of EA ,
accurate constant voltage regulation 12V at
universal AC input can be guaranteed. For high
efficiency, oscillator with frequency-reduction and
burst mode control is implemented. And EMI
performance is achieved with On-Bright
proprietary frequency shuffling technique and soft
gate driver design.
OB2223F offers power on soft start control and
protection coverage with auto-recovery features
including Cycle-by-Cycle current limiting, Over
Loading Protection, Output Short-Circuit
Protection, On-Chip OTP,VDD OVP, and UVLO.
