Product Introduction
The NCP12510 is a highly integrated PWM controller capable of delivering a rugged and high performance offline power supply in a tiny TSOP−6 package. With a voltage supply range up to 35 V, the controller hosts a jittered 65−kHz or 100−kHz switching circuitry operated in peak current mode control. When the power on the secondary side starts decreasing, the controller automatically folds back its switching frequency down to a minimum level of 26 kHz. As the power further goes down, the part enters skip cycle while limiting the peak current.
Over Power Protection (OPP) is a difficult exercise especially when no−load standby requirements drive the converter specifications. The ON Semiconductor proprietary integrated OPP allows harness the maximum delivered power without affecting the standby performance simply via two external resistors. An Over Voltage Protection (OVP) input is also combined on the same pin and protects the whole circuitry in case of optocoupler destruction or adverse open loop operation.
Finally, a timer−based short−circuit protection offers the best protection scheme, allowing precisely select the protection trip point without caring of a loose coupling between the auxiliary and the power windings.
