MP4032-1
Primary-Side-Controlled, Offline LED Driver
with Fully-Integrated Internal MOSFET
The Future of Analog IC Technology
DESCRIPTION
The MP4032-1 is a TRIAC-dimmable, primary-
side-controlled, offline, LED lighting driver with
an integrated 500V 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 secondary-side LED
current using primary-side information. It
simplifies LED lighting systems and increases
efficiency by removing the secondary feedback
components and the current-sensing resistor.
The MP4032-1 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 MP4032-1 is available in an SOIC8-7A
package.

Notes:
1) Exceeding these ratings may damage the device.
2) 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
