MIC2800  
Digital Power Management IC  
2MHz, 600mA DC/DC w/Dual  
300mA/300mA Low VIN LDOs  
Integrated power-on reset (OR function for all outputs)  
General Description  
Adjustable delay time  
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. The  
MIC2800 features a LOWQ™ mode, reducing the total  
current draw while in this mode to less than 30µA. In  
LOWQ™ mode, the output noise of the DC to DC  
converter is 75µVRMS, significantly lower than other  
converters which use a PFM light load mode that can  
interfere with sensitive RF circuitry.  
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  
The DC to DC converter uses small values of L and C to  
reduce board space but still retains efficiencies over 90%  
at load currents up to 600mA.  
Ideal for 1.8V to 1.5V conversion  
300mA output current from 1.8V input  
Output voltage down to 0.8V  
The MIC2800 is a µCap design, operating with very small  
ceramic output capacitors and inductors for stability,  
reducing required board space and component cost and it  
is available in fixed output voltages in the 16-pin  
3mm x 3mm MLF® leadless package.  
LDO2 – 300mA output current capable
