High Voltage Switcher for

Offline Power Supplies

The NCP112x products integrates a fixed−frequency peak current

mode controller with a low on−resistance, 650 V MOSFET. Available

in a PDIP−7 package, the NCP112x offers a high level of integration,

including soft−start, frequency−jittering, short−circuit protection,

thermal shutdown protection, frequency foldback mode and

skip−cycle to reduce power consumption in light load condition, peak

current mode control with adjustable internal ramp compensation and

adjustable peak current set point.

P SUFFIX

CASE 626B

During nominal load operation, the part switches at one of the

available frequencies (65 or 100 kHz). When the output power

demand diminishes, the IC automatically enters frequency foldback

mode and provides excellent efficiency at light loads. When the power

demand reduces further, it enters into a skip mode to reduce the

standby consumption down to no load condition.

The switcher also provides a jittered 65 kHz or 100 kHz switching

frequency to improve the EMI.
