Product Overview

The LM5009AMM/NOPB is a constant on-time non-synchronous Buck Regulator features all of the functions needed to implement an efficient, buck bias regulator. This high voltage regulator contains a 100V N-channel buck switch. The functional differences of the LM5009A is the minimum input operating voltage is 6V, the on-time equation is slightly different and the requirement for a minimum load current is removed. The regulator is based on a control scheme using an ON time inversely proportional to VIN. This feature allows the operating frequency to remain relatively constant. The control scheme requires no loop compensation. An intelligent current limit is implemented with forced OFF time, which is inversely proportional to Vout. This scheme ensures short-circuit control while providing minimum foldback. Other features include thermal shutdown, VCC undervoltage lockout, gate drive undervoltage lockout, maximum duty cycle limiter and a pre-charge switch.
  • Internal start-up regulator
  • No loop compensation required
  • Ultrafast transient response
  • On time varies inversely with input voltage
  • Operating frequency remains constant with varying line voltage and load current
  • Highly efficient operation
  • Precision internal reference
  • Low bias current
  • Intelligent current limit
  • Green product and no Sb/Br
