Monolithic Power Systems (MPS) MPQ4415A Synchronous Step-Down Converter
Monolithic Power Systems (MPS) MPQ4415A Synchronous Step-Down Converter offers 1.5A of continuous output current with excellent load and line regulation over a 4V to 36V input supply range. The MPQ4415A operates in a fixed frequency, peak-current-control mode to regulate the output voltage. An internal clock initiates a Pulse Width Modulation (PWM) cycle. The integrated Highside Power MOSFET (HS-FET) turns on and remains on until the current reaches the value set by the COMP voltage (VCOMP). When the power switch is off, it remains off until the next clock cycle begins. If the current in the power MOSFET does not reach the value set by VCOMP within 85% of one PWM period, the power MOSFET is forced off.
