The QM1001A0/A1 is a 6.5V -100V input, 1A output synchronous buck con verter. A constant on-time (COT) control architecture provides excellent load and line transient response. 

Additional features of the QM1001A0 works in FPWM mode operation and can be used for isolated voltage output application QM1001A0/A1 include peak and valley overcurrent protection, integrated VCC bias supply and bootstrap diode, precision enable and input UVLO, and thermal shutdown protection with automatic recovery.

 An op en-drain power good indicator provides sequencing, fault reporting, and output voltage monitoring. 

 QM1001A1 works with ultra-low IQ 30uA and PFM mode operation to achieve high light-load efficiency.
