Part Number: 1203P60, NCP1203D60R2G
Function: PWM Current-Mode Controller
Package: SOIC-8 or PDIP-8 Type
Manufacturer: ON Semiconductor
Pinouts:
Description
This is PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit Protection.
Housed in SOIC−8 or PDIP−8 package, the NCP1203 represents a major leap toward ultra−compact Switchmode Power Supplies and represents an excellent candidate to replace the UC384X devices.
Due to its proprietary SMARTMOS Very High Voltage Technology, the circuit allows the implementation of complete off−line AC−DC adapters, battery charger and a high−power SMPS with few external components.
With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz switching frequency, the controller features a high−voltage startup FET which ensures a clean and loss−less startup sequence.
Its current−mode control naturally provides good audio-susceptibility and inherent pulse-by-pulse control.
