Active Clamp Current Mode PWM Controller

The LM5026 PWM Controller contains all of the features necessary to implement power converters utilizing the active clamp / reset technique with current mode control. With the active clamp technique, higher efficiencies and greater power densities CAN be realized compared to conventional catch winding or RDC clamp / reset techniques. Two control outputs are provided, the main power Switch control (OUT_A) and the active clamp Switch control (OUT_B). The device CAN be configured to control either a P-Channel or N-Channel clamp Switch The main Gate driver features a compound configuration, consisting of both MOS and Bipolar devices, providing superior Gate drive characteristics. The LM5026 CAN be configured to operate with bias voltages over a wide input range of 8V to 100V. Additional features include programmable maximum duty cycle, line under-voltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable timeout delay, PWM slope compensation, soft-start, 1MHz capable Oscillator with synchronization input / output capability, precision reference and thermal shutdown.
