Product Overview

The LM5026MT is a Pulse Width Modulated (PWM) Controller contains all of the features necessary to implement power converters utilizing the active clamp and 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 and 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. It can be configured to operate with bias voltages over a wide input range of 8 to 100V. Additional features include programmable maximum duty cycle, line undervoltage lockout, cycle-by-cycle current limit and hiccup mode fault operation with adjustable timeout delay etc.
  • Current-mode control
  • 3A Compound main gate driver
  • High bandwidth opto-coupler interface
  • Programmable line undervoltage lockout (UVLO) with adjustable hysteresis
  • Versatile dual mode overcurrent protection with hiccup delay timer
  • Programmable overlap or deadtime between the main and active clamp outputs
  • Programmable maximum duty cycle clamp
  • Programmable soft-start
  • Leading edge blanking
  • Oscillator sync I/O capability
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
