DESCRIPTION
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.
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.
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.
The MP5410 is available in a small 16-pin QFN
3x3mm package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX)=(T
J
(MAX)-
T
A
)/
JA
. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operation conditions.
4) Measured on JESD51-7, 4-layer PCB.
