md12h can be replaced by IN582 Schottky diodes IN581 and IN582 series.
MD12H chip integrates pulse width modulation controller and power MOSFET, which is suitable for low-power off-line switching power supply.
The MD12H chip provides complete intelligent protection functions, including over current protection, under voltage protection, over voltage protection, over temperature protection and soft start function. Intermittent working mode can reduce the power consumption when the system is in standby mode. Buffeting technology contributes to EMI characteristics.
