quency peak current mode controller with a low on−resistance, 800 V MOSFET. Available in a PDIP−7 package, the NCP1136 offers a high level of integration, including soft−start, frequency−jittering, short−circuit protection, thermal shutdown protection, frequency foldback mode and skip−cycle to reduce power consumption in light load condition, peak current mode control with adjustable internal ramp compensation and adjustable peak current set point. During nominal load operation, the part switches at one of the available frequencies (65 or 100 kHz). When the output power demand diminishes, the IC automatically enters freque
