TPS61220DCKR Application Field and Working Principle

The TPS61220DCKR device is a DC-DC switching regulator that belongs to the portfolio of high-efficiency, high-density power management solutions from Texas Instruments. It is advanced, cost-effective, and easy to use integrated solution for various consumer applications. It provides up to 1A output current from a 2.5V - 5.5V input voltage range, with an adjustable output voltage from 0.95V to 5V using an external resistive feedback network.

TPS61220DCKR is a synchronous step-down DC-DC switching voltage regulator. It operates as an adjustable voltage regulator, providing an adjustable output voltage of 0.95V to 5V. This regulator provides a wide range of output voltage and current. It gives high switching frequency that enables the use of small surface mount components.

TPS61220DCKR devices have wide applications in embedded systems, notebook computers, mobile phones, portable devices, and any other systems requiring adjustable output voltage, high efficiency, and low noise.

Working Principle

TPS61220DCKR devices step-down voltage regulators integrate the high-side and low-side MOSFETs and controllers to form a complete synchronous step-down DC-DC switching regulator system. Its switching frequency can be adjusted from 375 kHz to 2.25MHz through external capacitors for maximum efficiency.

In typical applications, the TPS61220DCKR device\'s PWM Operation Mode operates with a fixed pulse-width modulated (PMW) frequency. The output voltage is adjustable from 0.95V to 5V using an external feedback network. The switching current is internally limited, making the TPS61220DCKR suited for higher power applications. The lowering of the current limit and the use of an external bypass switch can be used to control the output current dynamic and place it into a suspended power saving state, providing low quiescent current.

The Enable/Disable pin (EN) is an input that allows the user to control the enable logic level of the regulator. Connecting this terminal to ground will turn off the regulator. The Over Temperature Protection (OTP) circuit senses the junction temperature of the internal MOSFETs and limits the maximum temperature, preventing potential damage.

Conclusion

The TPS61220DCKR is an efficient, space-saving and cost effective DC-DC synchronous step-down voltage regulator for various consumer applications. Its features include an adjustable output voltage of 0.95V to 5V, high efficiency, low noise, and adjustable switching frequency. It is suitable for applications such as embedded systems, notebook computers and mobile phones, with an easy to use integrated solution.
