Current-Mode PWM Controller for Off-line Power Supplies

Overview

The NCP12510 is a highly integrated PWM controller capable ofdelivering a rugged and high performance offline power supply in atiny TSOP−6 package. With a voltage supply range up to 35 V, thecontroller hosts a jittered 65−kHz or 100−kHz switching circuitryoperated in peak current mode control. When the power on thesecondary side starts decreasing, the controller automatically foldsback its switching frequency down to a minimum level of 26 kHz. Asthe power further goes down, the part enters skip cycle while limitingthe peak current. The controller has integrated protections such as Over Power Protection (OPP), Over Voltage Protection (OVP) and short-circuit protections. NCP12510 is improved and pin compatible controller based on very popular flyback controller NCP1250.
