  3 Description
  The TPS560430 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 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 over the full load range. Soft-start and compensation circuits are implemented 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 TPS560430 is available in SOT-23-6 package.
  The TPS560430 regulator is an easy to use synchronous step-down DC-DC converter operating from 4-V to 36-V supply voltage. It is capable of delivering up to 600-mA DC load current in a very small solution size. The family has multiple versions applicable to various applications, refer to Device Comparison Table for detailed information.
  The TPS560430 employs fixed-frequency peak-current mode control. The device enters PFM Mode at light load to achieve high efficiency for PFM version. And FPWM version is provided to achieve low output voltage ripple, tight output voltage regulation, and constant switching frequency at light load. The device is internally compensated, which reduces design time, and requires few external components.
  Additional features such as precision enable and internal soft-start provide a flexible and easy to use solution for a wide range of applications. Protection features include thermal shutdown, VIN under-voltage lockout, cycle-by-cycle current limit, and hiccup mode short-circuit protection.
The family requires very few external components and has a pin-out designed for simple, optimum PCB layout.
