Descrição geral do produto

The LM5002MA is a 0.5A Non-synchronous Current-mode Switch-mode Regulator features all of the functions necessary to implement efficient high voltage Boost, Flyback, SEPIC and Forward converters, using few external components. This easy to use regulator integrates a 75 Volt N-channel MOSFET with a 0.5 Amp peak current limit. Current mode control provides inherently simple loop compensation and line-voltage feed-forward for superior rejection of input transients. The switching frequency is set with a single resistor and is programmable up to 1.5MHz. The oscillator can also be synchronized to an external clock. Additional protection features includes current limit, thermal shutdown, under-voltage lockout and remote shutdown capability.
  • Integrated high voltage bias regulator
  • Adjustable output voltage
  • 1.5% Output voltage accuracy
  • Current mode control with selectable compensation
  • Wide bandwidth error amplifier
  • Integrated current sensing and limiting
  • Integrated slope compensation
  • 85% Maximum duty cycle limit
  • Single resistor oscillator programming
  • Oscillator synchronization capability
  • Enable/under-voltage lockout (UVLO) Pin
  • Thermal shutdown
This 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.
