TPS65986ABZQZR

The TPS65986ABZQZR is an advanced power supply solution designed for portable consumer electronics applications. It is a generic, low-noise power management IC (PMIC) offering support for multiple output voltages, current limiting and voltage management. The primary application field for the TPS65986ABZQZR is consumer electronic devices that require multiple operating voltages or require a complex power management scheme. Examples include battery-powered consumer tablets, gaming systems, digital cameras and personal music players.

The TPS65986ABZQZR consists of a single integrated circuit. It is designed to provide a single, low noise and low quiescent current power supply with support for three separate output voltages. The main features of the TPS65986ABZQZR include a low-noise, voltage regulator, LDOs with low noise linear regulators, current limiting, overvoltage protection, internal clock oscillator and adjustable full performance tracking loop. In addition, the TPS65986ABZQZR satisfies many other power management requirements such as inrush current protection, temperature sensing, temperature compensation and overcurrent/overvoltage protection.

The TPS65986ABZQZR operates on two external power supplies: a 3.3V power supply for the internal control logic and a +3.3V to +30V input supply for external load. The IC’s integrated current limiting feature allows external loads to be safely operated at high voltage without damaging the IC. This is especially useful for portable devices that require multiple voltages in order to operate. The TPS65986ABZQZR also features an internal clock oscillator that ensures proper operation of the internal functions.

The TPS65986ABZQZR has three output channels that can deliver either a fixed or adjustable output voltage. The output channels can be powered independently by externally supplied voltage sources or are able to power each other after the corresponding enable signal has been activated. Maximum output load currents are 150mA and 150mA for each channel. The output currents can be precisely regulated via the integrated adjustable current limit circuit.

The TPS65986ABZQZR features overvoltage protection and overcurrent protection circuitry to protect the IC from damage due to incorrect user input. The integrated overvoltage protection monitoring circuitry protects the IC from damage due to an excessive input voltage. Similarly, the integrated overcurrent protection circuit prevents the IC from being damaged due to an excessive load current. The IC also includes internal temperature sensing circuitry allowing the IC to respond to changes in temperature and adjust its output voltages in order to maintain optimum performance.

Overall, the TPS65986ABZQZR is an advanced power management IC designed for portable consumer electronics applications. With its integrated voltage regulator and low-noise linear regulators, current limiting, overvoltage protection, temperature sensing and temperature compensation circuitry, the TPS65986ABZQZR is an attractive option for the design of portable consumer electronics. The IC’s versatile outputs, broad input voltage range, low output noise and low quiescent current make it well suited for modern consumer electronics designs.
