Convertidor dc-dc R1214Z221A-E2-F, Convertidor de subida, 100mA, Dual WLCSP-9-P1, 9 pines, 750 kHz

The Nisshinbo Micro Devices DC/DC Converter consists of an Nch MOSFET driver, an oscillator, a PWM comparator, a voltage reference unit, an error amplifier, an overcurrent protection circuit, an under voltage lockout circuit, an overvoltage protection circuit, a thermal shutdown protection circuit and 2 channel current drivers for white LEDs. It requires minimal external component count. By simply using an inductor, a resistor, capacitors and a diode, the white LEDs can be driven with constant current and high efficiency.
