TPS62007DGSR is a synchronous step-down DC/DC converter with an input voltage range between 2.7V and 5.5V and a high efficiency up to 96%. It utilizes a high-speed avalanche-rugged pulse width modulation (PWM) controller combined with two high-side integrated MOSFETs and one low-side integrated MOSFET. With a typical switching frequency of 1.2MHz, an output voltage as low as 0.8V can be achieved giving higher performance and the industry\'s most power-dense DC/DC converter for portable devices. In addition, its integrated High-Side/Low-Side current sense amplifiers provide a true resistor-less implementation with improved power efficiency.

Application field:

TPS62007DGSR is an ideal DC/DC power management solution for portable computing, handheld devices, and wireless products such as Smartphones and Tablets. These types of products often require battery backup power and the addition of other onboard components that consume high currents, making them suitable for the TPS62007DGSR. In addition, the DC/DC converter can also be used to increase efficiency and reduce overall power loss in automotive and industrial applications.

Working Principle:

The TPS62007DGSR DC/DC converter starts up at a high switching frequency and then cycles down to a programmed low frequency. By varying its internal frequency, the TPS62007DGSR maintains an efficiency value as high as 96%. This switching regulator dynamically optimizes power transfer and reduces power loss by modulating its frequency and duty cycle. It is possible to control the output voltage with a resistive divider and then set the desired output voltage. An integrated error amplifier adjusts the duty cycle of the internal switch to maintain the desired output voltage, regardless of load or input voltage changes.

TPS62007DGSR is a fully integrated and high-performance DC/DC converter, with low noise and battery ripple current, optimized power supply for portable products such as handheld devices or tablets in harsh environment. It is also configured with a programmable thermal warning and shutdown system ensuring part reliability. Its wide input voltage range, high efficiency, and low quiescent current makes it suitable for high-power applications. The TPS62007DGSR synchronous step-down DC/DC converter is a mainstay of many power management systems.
