The MP5410 is a high efficiency, current mode
step-up converter with four single-pole/double-
throw (SPDT) switches designed for low-power
bias supply application. The device can boost
dual-cell NiCd/NiMH or single-cell Li+ battery to
10V output voltage.
The MP5410 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 MP5410 to produce high
output voltage with high efficiency.

Over Temperature Protection
3x3mm QFN16 Package
In addition, the MP5410 can disconnect all
loads from input DC power supply. The
integrated schottky diode reduces external
parts to save critical board space.
APPLICATIONS
•
Dual-cell and Three-cell NiCd/NiMH or
Single-cell Li Battery Consumer Products
3D Glass Driver
Small LCD Displays Bias Supply
Digital Still and Video Cameras
Handheld Computers and PDAs
Cell Phones
The MP5410 features low shutdown current
allowing the part to draw less than 1µA off
current in shutdown mode. And it includes input
under voltage and over temperature protection.
