The Future of Analog IC Technology
MP4032-2
Offline LED Driver
with Fully-Integrated Internal MOSFET
DESCRIPTION
The MP4032-2 is a TRIAC-dimmable, offline
LED lighting driver with an integrated 600V
MOSFET. It can achieve a high power factor
and accurate LED current control for lighting
applications in a single-stage converter. The
proprietary real-current control can accurately
control the LED current.
The MP4032-2 has a power-factor-correction
function and works in boundary-conduction
mode that reduces power losses. The DRAIN
pin can supply current to the internal charging
circuit for start-up without a perceptible delay.
The proprietary dimming control extends the
TRIAC-based dimming range.
The multiple protections greatly enhance
system reliability and safety. These protections
include VCC under-voltage lockout, LED over-
voltage and over-current protections, short-
circuit protection, and over-temperature
protection.
The MP4032-2 is available in an SOIC8-7A
package.

Notes:
1) Exceeding these ratings may damage the device.
2) Guaranteed by design.
3) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/ θJA. 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.
4) The device is not guaranteed to function outside of its
operation conditions.
5) Measured on JESD51-7 4-layer board.
