Ürün Genel Bakış

The LM5034MTC/NOPB is a dual current-mode Pulse Width Modulated (PWM) Controller contains all the features needed to control either two independent forward/active clamp 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. The LM5034 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 dead-time of the active clamp gate drivers and adjustable maximum PWM duty cycle reduce stress on the primary side MOSFET switches. Additional features include programmable line under-voltage lockout, cycle-by-cycle current limit, hiccup mode fault operation with adjustable restart delay, 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
  • Active clamp gate driver for p-channel MOSFETs
  • Adjustable gate drive overlap time
  • 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 under-voltage lockout
  • Independently adjustable soft-start (each regulator)
  • Direct interface with opto-coupler transistor
  • Thermal shutdown
  • Green product and no Sb/Br

Uyarılar

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.
