MIC2800
Overview
The MIC2800 is a high performance power management IC, giving three output voltages with maximum efficiency. Integrating a 2MHz DC/DC converter with an LDO post regulator, the MIC2800 gives two high efficiency outputs with a second, 300mA LDO for maximum flexibility.
- 2.7V to 5.5V input voltage range
- 2MHz DC/DC converter and two stand-alone LDOs - LDO1: Low input voltage is powered directly from DC/DC converter for highest efficiency
- Integrated power-on reset (OR function for all outputs) - Adjustable delay time
- LOWQ® mode - 30µA Total IQ when in LOWQ® mode
- Tiny 16-pin 3mm x 3mm MLF® package DC to DC Converter
- Output current to 600mA in PWM mode
- LOWQ® Mode: NO NOISE Light load mode - 75µVRMS output noise in LOWQ® mode
- 2MHz PWM operation in normal mode
- >90% efficiency LDOs
- LDO1 input voltage directly connected to DC/DC converter output voltage for maximum efficiency - Ideal for 1.8V to 1.5V conversion - 300mA output current from 1.8V input - Output voltage down to 0.8V
