Summary and Features

• High efficiency, low cost, low component count solution

• Ideally suited as a standby supply in a larger 48 V input system

• The DPA-Switch IC integrates

− PWM controller and 220 V MOSFET switching device

− Accurate 400 kHz trimmed internal oscillator

− Accurate OV/UV protection

− Hysteretic thermal shutdown

− Overload, open loop and short-circuit protection

− Cycle skipping for regulation at no-load without a minimum load

• Small footprint 1.85" × 1", low overall height 0.9", two-layer PCB

• 100% surface mount construction

The products and applications illustrated herein (including circuits external to the products and transformer

construction) may be covered by one or more U.S. and foreign patents or potentially by pending U.S. and foreign

patent applications assigned to Power Integrations. A complete list of Power Integrations’ patents may be found
