The MP24894 is a high-efficiency step-down
controller. It is designed to operate in
continuous current mode (CCM) to power LEDs
of high-brightness with a wide input voltage
range of 6V to 60V.
The MP24894 employs a hysteretic control
architecture that accurately regulates LED
current with a feedback coming from an external
high-side current-sense resistor. This control
scheme optimizes circuit stabilization and fast
response time without loop compensation. Its
low 200mV average feedback voltage reduces
power loss and improves the converter’s
The MP24894 implements PWM and analog
dimming together through the EN/DIM pin.
The MP24894 includes thermal overload
protection in case of output overload.
The MP24894 is available in TSOT6 package.
