CURRENT MODE PWM POWER SWITCH

DESCRIPTION

FEATURES

AP2273 combines a dedicated current mode PWM

controller. It is optimized for high performance, low

standby power, and cost effective off- line flyback

converter applications in 40W~60W range.

AP2273 offers complete protection coverage with

automatic self-recovery feature including Cycle-

by-Cycle current limiting (OCP),SENSE short

protection, SENSE floating protection, over load

protection (OLP), and V_DDunder voltage lockout

(UVLO), over temperature protection (OTP), over

voltage(fixed or adjustable) protection (OVP).

The tone energy at below 20kHz is minimized in

the design and audio noise is eliminated during

operation.



Power on Soft Start Reducing MOSFET V_DS

Stress

Frequency shuffling for EMI



Extended Burst Mode Control For Improved

Efficiency and Minimum Standby Power Design

Audio Noise Free Operation

Fixed 65kHz Switching Frequency

Internal Synchronized Slope Compensation

Leading Edge Blanking on Current Sense Input

Good Protection Coverage With Auto Self

Recovery



 V_DDUnder Voltage Lockout with

Hysteresis(UVLO)

 Over Temperature Protection (OTP) with

auto-recovery

The AP2273 is available in SOT-26 package.

 Cycle-by-cycle over current threshold setting for

constant output power limiting over universal

input voltage range

 Overload Protection (OLP) with auto- recovery

 Over voltage Protection(OVP) with

auto-recovery
