The TPS60122PWPG4 is a monolithic step-down voltage regulator designed in a tiny, low-profile, 2.2 x 2.5 mm 2 mm, 8-lead wafer chip scale package. This device provides an easy-to-use power management solution for applications that require a small solution size, very low quiescent current, and wide input voltage range. It has been designed for reliable and efficient operation of power-sensitive integrated circuits, such as DSPs, microprocessors, RF transceivers, and MEMS.

The TPS60122PWPG4 belongs to the family of DC-DC switching regulators, also known as buck converters. These devices take a higher input voltage and switch it rapidly on and off to produce a regulated lower output voltage. The switching action can be synchronous or non-synchronous. A synchronous buck converter uses two transistors, an NMOS on the low side and a PMOS on the high side. The voltage is regulated by varying the duty cycle of the waveform, which is determined by the current through the control devices.

The TPS60122PWPG4 is a high efficiency synchronous buck converter specifically designed for power management in portable applications that require a small solution size, very low quiescent current and wide input voltage range. It operates from a wide input voltage range of 2.5V to 6V and provides a fixed, programmed output voltage of either 1.2V, 1.5V, or 1.8V. In addition, it can provide up to 1.2A of load current and delivers up to 80% of efficiency. It also features over-temperature, undervoltage lockout and over-current protection. This makes it an ideal choice for applications such as mobile phones, PDAs, and other portable devices that require low power consumption.

The typical applications of TPS60122PWPG4 include, but are not limited to, embedded systems, smart phones, tablets, digital media players, portable navigation devices and automotive applications. Additionally, this device is also suitable for use in digital TVs, gaming consoles and DHCP/INFANET interface cards.

The TPS60122PWPG4 is designed to provide excellent performance over a wide temperature range, from -40 to +85 °C. The device is available in a compact, 8-pin WLCSP package with a thermal pad to improve the thermal performance. Plus, it is compliant with the RoHS directive and is lead-free and Halogen-free.
