Overview
Current-Mode PWM Controller for Off-line Power Supplies NCP12510 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 req...
