The Texas Instruments TPS65288RHAR is a dual output PMIC (power management IC) with DC-DC switching regulators that regulates input voltage to output voltages by modulating the duty cycle of a high frequency switch. It is a high performance, low power, and low cost way to generate multiple regulated output voltages. It is capable of converting more than 1V input to +2.5V, +1.8V and +1.2V outputs and up to 16V input to +5V output.

As a high performance PMIC, the TPS65288RHAR is designed to deliver power to many different digital and analog circuits in a wide variety of applications. It is the ideal choice for powering displays, cameras, touch controllers, audio codecs, wireless and wired transceivers, multi-channel audio amplifiers and DSPs. The TPS65288RHAR is an ideal solution for portable electronics and handheld devices that require multiple output voltages from a single input voltage.

The TPS65288RHAR operates using a pulse width modulation (PWM) scheme in a voltage-mode control loop to regulate the output voltage. The TPS65288RHAR has two outputs, each with an adjustable voltage range of 0.75V to 5V. Each output is independently adjustable with a programmable soft start rate and PWM switching frequency. Further, the device provides input current limit protection and an adjustable output current limit to maximize system performance while preventing damage.

The TPS65288RHAR provides a very high level of EMI (electromagnetic interference) immunity and is robust against external transients and disturbances, making sure that it won\'t take performance away from other electronics in the system. This makes the device an ideal choice for applications with harsh environment requirements, such as automotive and industrial applications.

This PMIC also has other features such as a Programmable Frequency Waveform (PFW) and Hot Swap circuitry, allowing for better control flexibility and higher reliability. It has an integrated low drop-out (LDO) regulator and a temperature monitor that provide additional system protection in demanding temperature and environmental conditions. Further, the TPS65288RHAR has an integrated reset circuit with adjustable delay time, providing a reliable way to reset a system with the push of a button.

The TPS65288RHAR is the ideal choice for applications that require multiple output voltages, high power, low cost, and high EMI immunity. The advanced features built-in make this PMIC a suitable solution for power solutions in many portable and embedded applications.
