NCP1203 PWM Controller, Fixed Frequency, Flyback, Current Mode www.onsemi.com Housed in SOIC 8 or PDIP8 package, the NCP1203 represents a major leap toward ultracompact Switchmode Power Supplies and represents an excellent candidate to replace the UC384X devices.

Its currentmode control naturally provides good audiosusceptibility x = 4, 6, or 1 and inherent pulsebypulse control. A = Assembly Location When the current setpoint falls below a given value, e.g. the L = Wafer Lot output power demand diminishes, the IC automatically enters the so Y = Year W = Work Week called skip cycle mode and provides improved efficiency at light = PbFree Package loads while offering excellent performance in standby conditions. Because this occurs at a user adjustable low peak current, no acoustic noise takes place. 8 The NCP1203 also includes an efficient protective circuitry PDIP8 1203Pxx which, in presence of an output over load condition, disables the N SUFFIX AWL output pulses while the device enters a safe burst mode, trying to CASE 626 YYWWG 8 restart.
