SOT-23 (DBV)-6-8.12 mm² 2.9 x 2.8
The LV3842 is an easy to use synchronous step-down DC-DC converter capable of driving up to 600-mA load current. With a wide input range of 4 V to 36 V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.
The LV3842 employs 1.1-MHz switching frequency for small solution size. The LV3842 also has FPWM (forced PWM) version to achieve constant frequency and small output voltage ripple over the full load range. Soft-start and compensation circuits are employed internally which allows the device to be used with minimum external components.
The device has built-in protection features, such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown in case of excessive power dissipation. The LV3842 is available in SOT-23-6 package.
