Power Management Integrated Circuit (PMIC) plays an important role in modern electronic products due to its high efficiency and low power consumption. As a specialized PMIC, UCC29002DGK is highly reliable and can optimize system performance. This article includes UCC29002DGK application field and working principle to provide a better understanding of the device.
Application Field of UCC29002DGK
UCC29002DGK is designed for synchronous buck converters operating in the 13V to 24V input range. It enables the delivery of up to 5A current and has high efficiency up to 95.2%. In addition, it provides internal compensation and offers flexible output voltage adjustment by changing the resistor value.
UCC29002DGK is ideal for automotive, LED driver and consumer products, such as PC Mainboard, Headphone amplifier, VRM etc. In addition, this device is also suitable for power supplies in HVAC&R, Industrial Equipment, Low-end server, Power Management System and Communication System.
Working Principle of UCC29002DGK
The UCC29002DGK works as a switcher regulator. It outputs a regulated voltage from the input voltage. Regulated voltage is derived from the input voltage by using a high-frequency switching technique. UCC29002DGK consists of an internal power switch, an adaptive immune current limit circuit, a pulse width modulation (PWM) controller, a voltage regulator, a feedback voltage divider and a feedback amplifier.
The power stage begins with the Power switch, which is usually a power MOSFET. The energy is transferred from the input to the output through the switch. The adaptive immune current limit circuit is used to protect the power switch from over-current. Pulse width modulation controller is used to control the duty cycle of the switch which decides the output voltage.
The voltage regulator and the feedback voltage divider set the output voltage by comparing the output voltage with feedback voltage. The feedback amplifier feedbacks the output voltage to the pulse width modulation controller, so that the output voltage can be kept stable.
In addition, UCC29002DGK includes some features like Input UVLO (Under Voltage Lock Out), Output Over Voltage Protection (OVP) and Enable pin for more convenience.
Conclusion
UCC29002DGK is an ideal device for automotive, industrial and consumer products, which is optimized for synchronous buck converters with high efficiency, up to 95.2%, and low power consumption. Furthermore, it features internal compensation, flexible output voltage adjustment, Input UVLO, OVP and Enable pin.
