TPS60132PWP is a DC DC switching regulator from Texas Instruments, specifically a 3-A high current, 1mΩ internal power switch. It is a member of the PowerWise family of devices and is a pin-to-pin functional replacement for the discontinued regulator TPS60130, with improved performance and features over the predecessor. This device offers improved power efficiency and extended battery life, making it an ideal choice for many portable applications.

The TPS60132PWP is a synchronous buck regulator, which is a type of DC DC switching regulator used to convert an input voltage to a lower output voltage. Other types of DC DC switching regulators include flyback and SEPIC regulators, which share some common features with synchronous buck regulators, such as an inductor-based topology and a control feedback loop. However, the synchronous buck regulator has some distinct advantages over other types of regulators.

The Operational principle of the TPS60132PWP is based on "synchronous rectification”. This process enables switching power conversion without the need for diode rectifiers. The device uses an internal power switch (aka “high-side” or “MOSFET”) to efficiently control the current entering the inductor. The device also incorporates a driver circuit to control the switching activity and a voltage feedback loop to regulate the output voltage over a wide range of input and load conditions.

The TPS60132PWP is an ideal power solution for portable applications, where low power dissipation and small physical size are key considerations. This regulator is compatible with advanced low-voltage battery technologies such as Li-Ion batteries, as well as traditional NiCd and NiMH batteries. It features an enable input that can be used to enable/disable the device, and the enable mode can be set to either active low or active high. It also includes thermal shutdown and short circuit protection, as well as overvoltage protection.

The TPS60132PWP is intended for use in a wide range of applications, including portable media players, portable gaming devices, PDAs, cell phones, and digital still cameras. Due to its wide input range, small package size, and low power dissipation, the TPS60132PWP makes an ideal power solution for many of today’s newest portable devices.
