Product Overview

The LM5032MTC/NOPB is a dual current-mode Pulse Width Modulated (PWM) Controller contains all the features needed to control either two independent forward dc/dc converters or a single high current converter comprised of two interleaved power stages. The two controller channels operate 180° out of phase thereby reducing input ripple current. It includes a startup regulator that operates over a wide input range up to 100V and compound (bipolar + CMOS) gate drivers that provide a robust 2.5A peak sink current. The adjustable maximum PWM duty cycle reduce stress on the primary side MOSFET switches. Additional features include programmable line undervoltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable response time, PWM slope compensation, soft-start and a 2MHz capable oscillator with synchronization capability.
  • Two independent PWM current mode controllers
  • Integrated high-voltage startup regulator
  • Compound 2.5A Main output gate drivers
  • Synchronizable oscillator
  • Programmable maximum duty cycle
  • Maximum duty cycle fold-back at high-line voltage
  • Adjustable timer for hiccup mode current limiting
  • Integrated slope compensation
  • Adjustable line undervoltage lockout
  • Independently adjustable soft-start
  • Direct interface with opto-coupler transistor
  • Thermal shutdown
  • Green product and no Sb/Br
