MIC2826
Quad Output PMIC with HyperLight Load? DC-
DC, three LDOs, and I 2 C Control
General Description
The Micrel MIC2826 is a four output, programmable Power
Features
Management IC, optimized for high efficiency power
support in Mobile Application Processors, Co-Processors,
DSPs, GPS and Media Player chipsets. The device
integrates a single 500mA PWM/PFM synchronous buck
(step-down) regulator with three Low Dropout Regulators
and a 400kHz I2C interface that provides programmable
Dynamic Voltage Scaling (DVS), Power Sequencing, and
individual output Enable/Disable controls allowing the user
to optimally control all four outputs.

Power On After Fault (POAF) function
The 4MHz synchronous buck regulator features a patented
HyperLight Load? (HLL) architecture which minimizes
switching losses and provides low quiescent current
operation for high efficiency at light loads. Additional
benefits of this proprietary architecture are low output
ripple voltage and fast transient response throughout the
entire load range with the use of small output capacitors,
reducing the overall system size.
Three high performance LDOs are integrated into the
MIC2826 to provide additional system voltages for I/O,
memory and other analog functions. Each LDO is capable
of sourcing 150mA output current with high PSRR and low
output noise. A 2% output voltage accuracy, low dropout
voltage (150mV @ 150mA), and low ground current of
116μA (all three LDOs operating) makes this device ideally
suited for mobile applications.
The MIC2826 is available in a tiny 14-pin 2.5mm x 2.5mm
Thin MLF ? with a junction operating range from -40 ° C to
+125 ° C.
