TPS62050DGS is a highly integrated DC/DC buck switching regulator with high performance and low-profile WLCSP (Wafer Level Chip-Scale Package) that can help to reduce the BOM (Bill of Material) count in a mobile device. It is designed to provide a high-efficiency, low-profile, high-accuracy and low-noise power solution for mobile application such as cell phones, PDAs and Bluetooth headphone.

TPS62050DGS-based solutions are capable of delivering up to 750mA in a VOUT range of 0.8V to 3.3V with great accuracy. It helps to provide a wide variety of power management solutions with integrated components like MOSFETs, compensation, feedback and logic control. The device comes with a selectable dropout regulator (DOR) and low quiescent current for better Battery average life.

The TPS62050DGS is a DC/DC converter that efficiently step-downs an input voltage from 2.7V to 5.5V down to a user selectable output voltage of 0.8V to 3.3V. The chip features an adjustable switching frequency between 200kHz and 2MHz, allowing it to easily synchronize with other electrical components. The internal three-stage protection monitors and shuts down the switching regulator in the event of an OC, overtemperature, or input UVLO condition.

The DC/DC buck switching regulator in the TPS62050DGS is capable of automatically adjusting its duty cycle and switching frequency, allowing it to operate in a constant frequency or Pulse-Skip-Mode that allows the device to operate with high efficiency at light and medium loads. Under very light loads it can operate in pulse-skip mode, reducing the frequency and allowing the device to save power. On the other hand, at medium loads the device can operate in a constant switching frequency, providing accurate output voltage and fast transient responses.

The active frequency control improves the noise performance of the TPS62050DGS compared to similar devices on the market due to the advanced Pulse-Frequency-Modulation technology. The chip uses an Adaptive Frequency Dithering (AFM) technique for providing low ripple and noise performance at light loads, while still preserving a high level of efficiency.

The TPS62050DGS DC/DC buck switching regulator has numerous application fields ranging from cell phones and PDAs to Bluetooth headphones to other portable devices. Moreover, this device can be used in other applications such as automotive, wearables, IoT, and healthcare. In a nutshell, the TPS62050DGS is an ideal choice for applications requiring efficient and low-profile solutions with low quiescent current, automatic adjustment of the switching frequency, excellent noise performance, and low ripple output.
