TPS62625YFFT Application Field and Working Principle:The TPS62625YFFT is an advanced, low-power, multiphase synchronous buck DC-DC converter designed for applications operating from a single Li-ion battery cell, such as mobile phones and PDAs. The device integrates two synchronous buck DC-DC converters, each with its own fully integrated control circuitry, to minimize total on-board components and optimize overall efficiency and cost.The TPS62625YFFT is designed for space-constrained applications such as mobile phones, PDAs, and other portable products. It offers an efficient, multi-output power solution that integrates dual PWM-controlled synchronous buck converters, each with its own fully integrated control circuitry to minimize on-board components. The device supports up to two output voltages making it ideal for mobile device applications with multiple cores and core-logic chips.The design includes an input voltage range of 1.8 V to 4.45 V with a maximum current of 6A. It also consists of two synchronous buck regulators with a switching frequency of 1.2 MHz. Both converters can be independently adjusted from 0.6 V to 3.3 V in order to meet power requirements for multiple cores, as well as core-logic chips. The TPS62625YFFT also has a single-wire serial interface that gates power-sequence control of downstream peripheral devices.The working principle of the TPS62625YFFT is simple and straightforward. The input of the device is connected to a lithium-ion cell, while its two synchronous buck regulators are connected to two separate loads. When the device is powered on, it first establishes an input voltage. Once the input voltage is established, the two synchronous buck regulators take over and convert the input voltage into two regulated output voltages. The output voltages can be adjusted using the single-wire serial interface. After both output voltages are set, the device can then power on downstream peripheral devices. The TPS62625YFFT provides superior efficiency and switching frequency matching, as well as high-output voltage accuracy, ripple, and low-noise performance compared to other dark current compensation techniques. Additionally, its integrated features, external buck resistors, and single-wire serial interfaces simplify design and system integration.In conclusion, the TPS62625YFFT is an advanced, low-power, multiphase synchronous buck DC-DC converter designed for applications operating from a single Li-ion battery cell, such as mobile phones and PDAs. It offers an efficient, multi-output power solution that integrates two synchronous buck converters, each with its own fully integrated control circuitry, to minimize on-board components and offer superior efficiency, voltage accuracy, and low-noise performance.
