Texas Instruments TPS560430 | Demoboard SLVUB52

Description

EVM Features• 4-V to 36-V input voltage range• Accurate 5-V output• Up to 600-mA output current• Switching frequency 1.1 MHz• Hiccup mode short current protection• Internal compensationThe TPS560430 is an easy to use synchronous step-down DC-DC converter capable of driving up to 600 mA. With a wide input range of 4 V to 36 V, the device is suitable for a wide range of applications from industrial to automotive for power conditioning from an unregulated source. The TPS560430 has 1.1-MHz and 2.1-MHz operating frequency versions for either high efficiency or small solution size. The TPS560430 also has FPWM (forced PWM) version to achieve constant frequency and small output voltage ripple at light load. Soft-start and compensation circuits are implemented internally which allow the device to be used with minimized 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 TPS560430 is available in a low profile 6-pin SOT-23-6 package.
