The MP3412 is Monolithic Power Systems’ new synchronous, fixed frequency, high efficiency step-up WLED driver. It features an output load disconnect function in a low profile 6-lead Thin-SOT23 package. The MP3412 can start up from an input voltage as low as 0,8 V and provides in-rush current limiting as well as output short circuit protection; open load protection is also integrated. A switching frequency of 1 MHz minimises overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors, while current mode PWM control with internal compensation reduces external parts, further saving critical board space.
The device features low shutdown current of under 1 μA. The true output disconnect feature allows the output to be completely discharged in shutdown. It also limits the inrush of current during startup, minimising surge current seen by the input supply.
