DESCRIPTION
The MP4689 is a high voltage input step-down
switching regulator to deliver a constant current
of up to 1A to high power LEDs. It integrates a
high-side high voltage power MOSFET with a
current limit of 2.5A (typical value). The wide
4.5V to 100V input range accommodates a
variety of step-down applications, making it
ideal for automotive, industrial and general
lighting applications. Hysteresis current mode
control is applied for very fast response, which
makes the 20kHz dimming frequency possible.
MPS’s proprietary feedback control scheme
minimizes the number of external components
while delivering a LED current with typical ±3%
accuracy.
The switching frequency is up to 1MHz, thus
allowing for small component size. The thermal
shut down and short circuit protection provide
reliable, fault tolerant operations. A 170µA
quiescent current allows its use in battery-
powered applications.
The MP4689 is available in SOIC8 with
exposed pad 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
operating conditions.
4) Measured on JESD51-7 4-layer board.
