Introduction
TPS76733QPWPG4 is a positive adjustable, high current, low dropout linear-mode voltage regulator. It is designed to operate over a wide input voltage range with a maximum output current of 7 A. The device has an adjustable output voltage and is designed in order to draw very low quiescent current (30 uA). It is packaged in a 2mm x 2mm QFN and is available in thermally enhanced packages.
Application Field and Working Principle
Application Field
1. Power management of smartphone, tablet and other ultra-thin electronic products
2. Point-of-load conversion
3. Mainstream DDR memory system voltage regulation
4. Recording and information storage equipment power management
Working Principle
TPS76733QPWPG4 is a voltage regulator in the family of PMIC (Power Management IC) voltage regulators, which is a type of Linear voltage regulator. It is a positive adjustable, high current, low dropout linear-mode voltage regulator. It features an adjustable voltage range from 0.8V to 5V. It can deliver up to 7A output current with less than 10mV dropout voltage, and is able to hold the exact programmed output voltage despite transient and thermal variations.
TPS76733QPWPG4 operates by monitoring and comparing the output voltage to a internal reference voltage. The output voltage is compared to the internal reference voltage and the error amplifier computes the difference between the two voltages. This difference is also known as the error voltage. When the feedback voltage is less than the reference voltage, the error amplifier produces an output voltage that controls the gate of an external pass transistor and forces the output voltage upward until the two are equal. Conversely, the error amplifier causes the output voltage to go downward until the two voltages match.
Key Features
1. Low Dropout voltage
2. Wide Adjustable Input Voltage Range: 0.8V to 5V
3. High Output Current: up to 7A
4. Current Limit, Overvoltage and Thermal Protection
5. PowerGood, VID Pin and Control Register Programming
6. Thermal Enhanced Packages
Conclusion
TPS76733QPWPG4 is an ideal voltage regulator for application in limited space due its small form factor, high efficiency and wide operating temperature range. Additional protection is also provided by building in overvoltage protection, an internally-set current limit, and thermal protection.
