Description: OB2279 Current Mode PWM ControllerFreq S huffling with Latch Shutdown OB2279 is offered in SOP-8 and DIP-8 packages. G ENERAL DESCRIPTION OB2279 is a highl y integ rated current mode PWM control IC optimized fo r high performance, low s tandby pow er and cost effe ctive offli ne fly back converter applications. PWM switching frequenc y at norm al operat ion is externally programmable and trim med to tigh t range. At no load or ligh t load condition, t he IC operates in e xtended ‘bu rst mode’ to minimize s witching loss. Lower stan dby p ower an d high er conversion efficiency is thus achieved. VDD low startup current and low operating curre nt contribute to a reliable po wer on startu p design with
