Introduction: UCC25701NG4

UCC25701NG4 is a high-efficiency, compact AC/DC switcher designed for automotive and other applications. The chip offers high-density power conversion and flexibility to reduce the design cost and size of the power supply. It operates from 8.2 - 38V input and offers output currents up to 2.5A with a power efficiency of up to 94%. The chip also provides an adjustable frenquency oscillator and programmable soft start ramp control.

Application Field and Working Principle: UCC25701NG4

The UCC25701NG4 is primarily used for automotive and other applications requiring a compact, high-efficiency power converter. It is suited for a wide range of automotive applications from charging cell phones to powering light-emitting diodes (LEDs). Other applications include powering sensor nodes, SBCs, lower watt solar modules and PoE applications, in addition to a variety of other portable and home appliances.

AC/DC Conversion

The UCC25701NG4 converts an AC input voltage between 8.2 and 38V into a DC output voltage, which is selectable by an external resistor. It uses a peak current-mode switch-mode converter with a resonant-mode control scheme. This type of converter eliminates the need for bulky power factor correction and output filtering.

Soft switching

The UCC25701NG4 features a soft-switching function, which reduces switching losses and increases power efficiency. It also helps minimize EMI and minimize the overall system cost.

Adjustable oscillator

The adjustable oscillator enables the user to adjust the frequency of operation to optimize the efficiency of the converter over different voltage ranges.

Programmable soft start ramp control

The UCC25701NG4 offers an adjustable soft start ramp control which gives the user the possibility to set the output voltage ramp-up time accordingly, depending on the application.

Conclusion

The UCC25701NG4 is a high-efficiency, compact AC/DC switcher designed for automotive and other applications. The chip offers high-density power conversion and flexibility to reduce the design cost and size of the power supply. It operates from 8.2 - 38V input and offers output currents up to 2.5A with a power efficiency of up to 94%. The chip also provides an adjustable frenquency oscillator and programmable soft start ramp control for optimized performance.
