Datasheet Summary

2A, 1.5 MHz PWM step-down switching regulator with synchronous rectification Features - 1.5MHz fixed frequency PWM with current control mode - 2A output current capability .. - Typical efficiency: > 90% - - - - - - - - 2% DC output voltage tolerance Two versions available: Power Good or Inhibit Integrated output over-voltage protection Non switching quiescent current: (typ) 1.5mA over temperature range RDSON (typ) 100mΩ Utilizes tiny capacitors and inductors Operating junction temp. -30°C to 125°C Available in DFN6 3x3mm exposed pad Moreover, since the required synchronous rectifier is integrated, the number of the external ponents is reduced to minimum: a...
