The TPS50601MHKHV is a DCDC switching regulator packet comprising a synchronous buck integrated circuit (IC) with an external power MOSFET. It is an efficient, low-noise, 45V input voltage regulator, for up to 6A load current solutions. It comes with an integrated fast switching buck controller, TPS50601, plus a synchronous N-channel power MOSFET switch and a compensation network on the same chip. The device supports up to 12 W of continuous output power.

The TPS50601MHKHV is designed to provide a cost-effective and efficient solution for a wide range of automotive, industrial, and communications applications. It is designed to provide a regulated output current while consuming very low quiescent current. The device integrates a high-side switch, and an output current limiter to reduce the risk of component over temperature and short circuits. The TPS50601MHKHV also provides a power-good output flag, as well as soft-start, thermal protection, fault detection, and cycle-by-cycle current limit protection.

The working principle of the TPS50601MHKHV is quite simple. When the input voltage is applied, the internal synchronous P-channel and N-channel MOSFETs are turned-on and the integrated buck controller adjusts the pulse width of the switches in order to regulate the output voltage. The output voltage can be set externally using two resistors. The internal current limit, as well as the current limit rise rate, is set using one resistor too. The device also supports a low shutdown current, and a Programmable Frequency Pin.

Thus, the TPS50601MHKHV is a cost-effective and efficient DC-DC switching regulator that is ideal for automotive, industrial, and communications applications. Its features and advantages, such as fast transient response, low quiescent current, on-chip power MOSFET, and optimized EMI filter, make it an ideal choice for high current power management applications. In addition, its Protection features, such as cycle-by-cycle current limit, short-circuit protection, and output current limitation, provide power or circuit malfunction protection, as well as thermal protection.
