MP24894GJ-Z high-efficiency step-down controller original spot
MP24894GJ-Z
6V-60V Input Step-Down WLED Controller with Hysteresis Control, DC and PWM Dimming Control
Product Description
The MP24894 is a high efficiency buck controller. With a wide input operating voltage range of 6V to 60V, it uses continuous current mode (CCM) to power high brightness LEDs. The MP24894 uses a hysteretic control structure to precisely regulate the LED current through feedback from an external high-side current sense resistor. This control method optimizes circuit stability and fast response time without loop compensation. Its low average feedback voltage of 200mV reduces power losses and improves converter efficiency. The MP24894 provides PWM and analog dimming via the EN/DIM pin. The MP24894 has thermal overload protection when the output is overloaded. The MP24894 is available in a TSOT6 package.
