DESCRIPTION
The MP3301 is a step-up converter designed to
drive WLEDS arrays from a single-cell, lithium-ion
battery. The MP3301 uses a current-mode, fixed-
frequency architecture to regulate the LED
current, which is measured through an external
current sense resistor. Its low 200mV feedback
voltage reduces power loss and improves
efficiency. The MP3301 turns off in the presence
of an open-circuit over-voltage condition.
The MP3301 includes under-voltage lockout,
current limiting, and thermal-overload protection
to prevent damage in the event of an output
overload.
The MP3301 is available in a small 5-pin TSOT23
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 θ
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
)/θ
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
operating conditions.
4) Measured on approximately 1” square of 1 oz copper.
