General Introduction to Voltage Regulators

A voltage regulator is an electronic/electrical device that adjusts and limits the voltage within a certain range to ensure that a system runs safely and stably. Voltage regulators are often used to protect components from sudden voltage spikes or to maintain a constant output voltage level across different loads.

Voltage regulators come in a variety of types, such as linear voltage regulators, switching voltage regulators, integrated voltage regulators and adjustable voltage regulators. Of these, the most common type today is the switching voltage regulator, which offers improved efficiency and better power management.

DC-DC Switching Regulators

DC-DC switching regulators are a type of switching voltage regulators, referred to as buck or boost regulators, whichstep up or step down the voltage from a power source. These type of regulators often have a higher switching frequency than other types of regulators, allowing for greater efficiency and power conversion ratios. In addition, these regulators often have short transient response times which enable them to handle sudden changes in loads.

The TPS62701YZFR is a buck regulator, meaning that it steps down voltage supplied to an external device. This regulator integrates a high-side N-channel MOSFET that can provide up to 1.1A current limit while offering a wide range of output voltage levels that can be set using two external resistors.

TPS62701YZFR Overview

The TPS62701YZFR is a high output current and low quiescent current power-saving buck regulator with Cycle-By-Cycle current limit. Its high-side N-channel MOSFET is capable of delivering up to 1.1A output current effortless. It also has a wide range of output voltages from 0.84V to 1.8V that can be programmed with two external resistors.

This regulator has an efficient operation at heavy load and provides excellent load-transient response characteristics. Its low operating and standby quiescent current consumption provides low operating power target and high system efficiency in light load conditions. It comes with built-in over current protection and thermal shutdown protection.

In addition, the TPS62701YZFR\'s high frequency operation (1MHz nominal PFM mode, 5MHz forced PWM mode) provides compact size with minimal external components. Its low-noise operation at light load and shutdown mode make it ideal for powering processors and other sensitive components.

TPS62701YZFR Application Field and Working Principle

The TPS62701YZFR is most often used in applications that require high output current and high efficiency with low operating and standby quiescent current consumption. It can be used in many applications such as charging, powering, powering of embedded processors, and so on. Working with voltages from 2.3V to 5V, this regulator has been specificallydesigned for low quiescent current.

The regulator is based on a high-side N-channel MOSFET and operates in a hysteretic modeto regulate the output voltage. Its adjustable operating frequency (1MHz nominal PFM mode, 5MHz forced PWM mode) provides better noise immunity and fast transient response, in addition to its cycle-by-cycle current limit protection.

In sum, the TPS62701YZFR is a high-performance power-saving buck regulator that can provide excellent load-transient response characteristics with a wide range of output voltages, low operating and standby quiescent currents, and cycle-by-cycle current limit protection.
