MP5414
PMU for 3D Glasses
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP5414 is a highly-efficient fully-integrated
PMU with a current-mode step-up converter,
four single-pole/double-throw switches, low
drop-out, and a battery charger designed for
battery-powered supply applications.

1.8V Low Voltage Start-Up
1.8V to 5.5V Input Range
Output Disconnect
Integrated Power MOSFET and Schottky
Diode
The step-up converter can start-up from an
input voltage as low as 1.8V. It uses a current-
limited variable-frequency control algorithm to
optimize efficiency and minimize external
component size and cost. The internal low-
resistance N-Channel MOSFET switch can
withstand up to 10V, allowing the MP5414 to
produce a high output voltage with high
efficiency from a dual-cell NiCd/NiMH or single-
cell Li-ion battery. In addition, the step-up
converter can disconnect all loads from the
input DC power supply.

No External Sense Resistor
No External Reverse Blocking Diode
The charger features constant-current and
constant-voltage charging modes with
a
programmable charge current (50mA to
300mA), trickle-charge capability, and a charge-
status indicator. Charging is enabled with an
input voltage greater than 3.5V, and is disabled
when unplugged from the AC adaptor. The
charger does not need an external reverse-
blocking diode.

Stable With Low-ESR Output Capacitor
The low-dropout linear regulator operates with
low noise from a 2.7V-to-6.5V input voltage,
and regulates the output voltage with 2%
accuracy from 1.25V to 5V.
APPLICATIONS
The MP5414 is available in a 4mm x 5mm 28-
pin QFN package.
