High-Voltage Switcher for

Low Power Offline SMPS

The NCP107x products integrate a fixed frequency current mode

controller with a 700 V MOSFET. Available in a PDIP−7 or SOT−223

package, the NCP107x offer a high level of integration, including

soft−start, frequency−jittering, short−circuit protection, skip−cycle, a

maximum peak current set point, ramp compensation, and a Dynamic

Self−Supply (eliminating the need for an auxiliary winding).

Unlike other monolithic solutions, the NCP107x is quiet by nature:

during nominal load operation, the part switches at one of the available

frequencies (65, 100 or 130 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 a no load condition.

Protection features include: a timer to detect an overload or a

short−circuit event, Overvoltage Protection with auto−recovery and

AC input line voltage detection.

For improved standby performance, the connection of an auxiliary

winding stops the DSS operation and helps to reduce input power

consumption below 50 mW at high line.
