What's the difference between MP4033 and MP4030?

MP4033 provides off-line single-stage LED driving scheme, which is suitable for isolated and non-isolated schemes within 50W.

The patented primary constant current control scheme simplifies the circuit and saves components;

The patented fast power supply scheme can realize the system.

Good linear adjustment rate, compatible with traditional power grid voltage fluctuation and LED current change rate.

Patented intelligent judgment dimming mode technology to optimize TRIAC dimming compatibility;

Programmable NTC temperature protection function;

Can support external PWM dimming signal;

Can support two channels of warm/cold color mode adjustment;

Rich protection against open circuit, short circuit, overcurrent and overheating;

There are three packaging options: MSOP 10, SOIC8 and SOIC 14.

Mp4030–WLED driver IC with triac dimming (single-stage PFC) primary control, isolated bulb lamp, fluorescent lamp scheme and scheme within 30W are acceptable. The advantages of MPS4030/2 1 are: 1. Integrated PFC, high power factor; 8W design, at 260V, PF=95%, 85V = 99%. 2. Source control, omitting optocoupler and related circuits, reducing BOM cost. 3. Unique MOSFET control technology has lower requirements for MOSFET and fast recovery diode. For a few schemes, expensive MOSFET and diode must be selected to further reduce BOM cost. 4. Support the traditional dimming mode (because of the unique MOSFET control technology).
