Output Power Chokes for ON Semiconductor NCP-1207 Controller

ICE Components, Inc. announces a new series of output power chokes that greatly simplify the design of flyback power supplies based upon ON Semiconductor's NCP-1207 controller. ICE's I04 series, designed in collaboration with ON Semi, is designed to work as part of a second stage filter with the most popular output voltages and currents, thereby reducing time to market.

The I04 series' cost effective, toroid-based design uses Micrometals cores to assure long-term thermal stability. Current ratings range from 3.3A to 16A, inductances range from 3.0 uH to 34.8 µH with no load and DCR's as low as 2.0 mΩ. ICE's I04 output power chokes are used in flyback converters using ON Semi's NCP-1207 current-mode controller for free running, quasi-resonant operation, as well as other popular flyback controllers. Applications include notebook and offline battery chargers, consumer electronics, medical power supplies, etc. ICE's I04 series brings great simplification to the design cycle because it was designed in collaboration with ON Semi and features:

Several loaded inductance/DCR values at each output current, allowing engineers to optimize ripple/efficiency based upon applications needs.

Pre-engineered solutions for MIN/MAX frequency/current combinations that simplify the cumbersome second stage filter design caused by the variable frequency in quasi-resonant applications.

Cost effective, powdered iron core designs utilizing Micrometals' cores to prevent thermal aging.

Parts in this series are available in trays with prices as low as $0.27. Individual parts pricing will vary due to volume, configuration and shipping destination.
