UCC25706DGKG4 is a family of integrated circuits (ICs) designed by Texas Instruments’ to optimise offline switcher design for power supplies. This family of ICs is a part of their Power Management Integrated Circuits (PMICs) portfolio which offers AC-DC converter circuits along with offline switcher part. It is a versatile IC that allows the designer to meet the need of a wide range of applications. This article will discuss the application field of UCC25706DGKG4 and the working principle of the IC.

Application Field

The UCC25706DGKG4 is a monolithic offline switcher with synchronous rectifier and peak current mode control. This IC supports different topologies and it can accept an input voltage ranging from the universal AC input to more critical bias power supplies. It is ideal for both single-ended and multiple-ended forward converters, as well as multiple-ended offline flyback converters.

This chip is designed to optimise the overall cost and reliability of the offline power supply through design innovations such as adjustable on-times, wide dip compensation range, quiescent current ripple off mode, integrated soft start and output overvoltage protection. All the features are integrated on to the IC, which eliminates the requirement of add-on components and hence reduces the cost of developing a power supply.

The list of products covered by UCC25706DGKG4 includes smartphones, industrial systems, and consumer electronics where efficiency and cost are important design considerations. Apart from this, it is ideal for telecom, automotive, medical and instrumentation applications.

Working Principle

UCC25706DGKG4 controls switched mode power supplies using peak current mode control. There are two main components in this IC; primary side control circuit and a synchronous rectifier. The power supply is connected to the primary side and monitored by the primary side control circuit. The control circuit monitors and regulates the output power of the power supply by pulse width modulation.

The primary side control circuit has four main parts: an error amplifier, compensation circuitry, a current sense circuit and a PWM comparator. The error amplifier compares the output voltage and the feedback voltage while the compensation circuitry provides control over the stability of the control loop. The current sense circuit monitors the drain-source current of the power transistor while the PWM comparator compares the output of the error amplifier and the current sense circuit.

The synchronous rectifier on the other side of the IC is used to reduce switching losses. It allows a power semiconductor to switch off when its current starts to decrease and turns it on again when the current starts to increase. This function reduces switching losses and provides better load and line regulation.

UCC25706DGKG4 supports two independent selectable operating modes for achieving maximum efficiency. One is a quiescent current ripple OFF mode which ensures that no current flows through the power dos after the power-on transition until the output voltage reaches a predetermined level. The other mode is a cycle-by-cycle current limit mode which further reduces power consumption by setting an upper limit for continuous switching cycles.

Overall, the UCC25706DGKG4 provides the flexibility for a wide range of applications and the peak current mode control with synchronous rectifier provides excellent load and line regulation. It also offers improved power efficiency, low EMI and system cost.
