| Part: | LM5026MT |
| Category: | Power Management => Regulators => Switching Regulators |
| Description: | 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.
