General Description
The MIC2810 is a high performance power management
IC, integrating a 2MHz DC/DC switcher with two 300mA
LDOs. The MIC2810 features a LOWQ
mode, reducing
the total current draw while in this mode to less than 30A.
In LOWQ
mode, the output noise of the DC/DC converter
is 53VRMS, significantly lower than other converters that
use a PFM light load mode that can interfere with sensitive
RF circuitry.
The MIC2810 is a Cap design, operating with very small
ceramic output capacitors and inductors for stability,
therefore, reducing required board space and component
cost. It is available with fixed output voltages in a 16-pin
3mm x 3mm MLF
leadless package.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
