  • 2A output current.
  • Up to 93% peak efficiency.
  • 87% typical efficiency at 1mA.
  • 23µA typical quiescent current.
  • 4MHz PWM operation in continuous mode.
  • Ultra-fast transient response.
  • Low ripple output voltage.
  • 14mVpp ripple in HyperLight Load mode.
  • 5mV output voltage ripple in full PWM mode.
  • 0.01µA shutdown current.
  • Thermal-shutdown and current-limit protection.

MIC23150 4MHz, PWM, 2A Buck Regulator with HyperLight Load® General Description The MIC23150 is a high-efficiency 4MHz 2A synchronous buck regulator with HyperLight Load® mode. HyperLight Load provides very high efficiency at light loads and ultrafast transient response which is perfectly suited for supplying processor core voltages. An additional benefit of this proprietary architecture is very low output ripple voltage throughout the entire load range with the use of small output capacitors. The tiny 2mm × 2mm Thin DFN (TDFN) package saves precious board space and requires only three external components. The MIC23150 is designed for use with a very small inductor, down to 0.47µH, and an output capacitor as small as 2.2 µF that enables a total solution size, less than 1mm height.
