TPS62120DCNR is a synchronous buck converter chip from Texas Instruments, providing efficient and compact solutions for various power designs. This DC-DC controller integrates a high-side P- channel MOSFET power switch along with low side constant current source as the driver of external P- channel MOSFET. By using a wide input voltage range, it is capable of supplying output voltage as low as 0.6V making TPS62120DCNR a perfect fit for applications requiring low power DC-DC converter.

TPS62120DCNR application fields mainly include multimedia applications, portable computing, industrial and others. Its main features are a wide 4.5V to 24V input voltage range, adjustment-free output voltage of 0.6V providing up to 1A switch current, integrated current limit and Hz/timer based adjustable frequency PWM. In addition, its frequency is manually adjustable to optimize system performance.

The large switch current capability of the integrated P-channel MOSFET makes TPS62120DCNR suitable for applications requiring current delivery up to 1A.

The internal working principle of TPS62120DCNR is based on synchronous buck converter topology. It uses an integrated high side P-channel switch and low side constant current source to provide switching control and power flows to output. During each switch cycle, the controller begins by turning on high side switch and allows current to flow through the inductor. As the switch flips to OFF state, the stored energy in the inductor is transferred to the output. The internal current limit is utilized to lower the switch current in case of overload conditions. In addition, the Hz/Timer based PWM allows dynamic adjustment of switching frequency to reduce converter losses and enhance loop stability at extreme loads.

TPS62120DCNR offers a stable output voltage with fast line reaction time that is essential for applications requiring reliable power delivery. It also provides adjustable current limit settings, allowing users to achieve over current protection according to the system demand.

In conclusion, TPS62120DCNR is an ideal fit for applications requiring low power DC-DC converter with flexible output voltage and current settings. With its wide input and excellent performance, it is perfect for any low voltage, current intensive applications that require superior performance and reliability.
