The XC9129D45CDR-G is ideal for use in a wide range of applications, including high-current and low-current applications, as well as direct current or alternating current applications. The XC9129D45CDR-G is a perfect choice for battery-powered applications such as mobile phones, digital cameras, notebook computers, handheld gaming consoles, and portable music players. It also can be used in a wide range of applications that require low-voltage or stable power, such as power amplifiers, car audio amplifiers, and display drivers.

Key Specifications

The XC9129D45CDR-G PMIC supports several input and output voltage settings. Its primary switching frequency is 450 kHz and it provides a maximum current load of up to 6A. Its voltage accuracy range is 1.2% and its ripple noise is 60mVp-p. It also has over-voltage and over-temperature protection, short-circuit protection, and under-voltage lockout (UVLO).

Working Principle of the XC9129D45CDR-G

The XC9129D45CDR-G works by controlling an oscillator at its switching frequency. This oscillator is connected to a pulse-width-modulated (PWM) controller, which controls the frequency and duty cycle of the output waveform. The output of the PWM is sent to a MOSFET, which is a voltage-controlled switch. This MOSFET is responsible for supplying the output voltage. The output voltage is determined by the duty cycle of the MOSFET and the output voltage range is set by changing the input voltage.

The XC9129D45CDR-G includes several protection features that keep the system safe and improve the overall system performance. These protection features include over temperature protection (OTP), short circuit protection (SCP), under voltage lockout (UVLO), and an over-voltage protection (OVP) circuit. These protection circuits provide a reliable and safe operation of the system.
