MP24893 Step-Down White LED Driver with Wide 6V to 36V Input Voltage
DCRIPTION
The MP24893 is a high efficiency step-down converter digned in continuous current mode for driving the high brightns LEDs from wide input voltage of 6V to 36V.
The MP24893 employs hysteretic control architecture to regulate a highly accurate LED current, which is measured through an external high-side current-sense ristor. Moreover, this control scheme provid optimal circuit stabilization and a very quick rponse time without loop compensation. Its low 200mV average feedback voltage reduc power loss and improv the converter efficiency.
The MP24893 implements PWM and og dimming together through the DIM pin.
The MP24893 includ under-voltage lockout, thermal overload protection to prevent damage in the event of an output overload.
The MP24893 is available in TSOT23-5 and QFN6 packag.
