NCP1203P - Brand New ON Semiconductor AC DC Converters, Offline Switchers
-
Description
PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit Protection
The NCP1203P is a type of offline switcher and AC DC converter that serves as a PWM current-mode controller. It comes in an SOIC-8 or PDIP-8 package and is a significant advancement towards compact switch mode power supplies. The device is an excellent replacement candidate for the UC384X devices.
Thanks to its advanced SMARTMOS™ Very High Voltage Technology, the circuit can implement complete offline AC-DC adapters, high-power SMPS, and battery chargers with minimal external components. The controller features a switching frequency of 40 kHz, 60 kHz, or 100 kHz operating at fixed switching frequency, with a high-voltage startup FET that ensures a clean and loss-less system start-up sequence. The current-mode control of the NCP1203P provides excellent audio-susceptibility and inherent pulse-by-pulse control. It also offers short circuit protection and standby functions.
Specifications and features
- Power Management: PWM controller
- Packaging: PDIP-8 or SOIC-8
- Operating Temperature: -40 °C to 125 °C
Application Scenarios
The NCP1203P is extensively used in the production of small to medium-sized AC-DC power supplies for various applications like vending machines, audio systems, printers, servers, communication equipment, and others.
Comparison
Advantages- High-voltage startup FETs and fixed switching frequency operation ensure a clean and loss-less system start-up sequence.
- The current-mode control provides excellent audio-susceptibility and inherent pulse-by-pulse control.
- Short circuit protection and standby functions provide additional safety.
Disadvantages- The NCP1203P is not suitable for high-current applications as its maximum output power is somewhere around 70-80 watts.
- The PDIP-8 and SOIC-8 packages limit the available configuration of the overall system adaptation.
