TPS65133DPDR application field and working principle
The TPS65133DPDR is a highly-integrated power management integrated circuit (PMIC) designed to provide supply voltage and current requirements for various digital systems. It is ideal for use in consumer electronics, such as portable devices and mobile phones, where its single-supply feature simplifies power management. The TPS65133DPDR offers low noise and low quiescent current, making it well suited for battery powered applications. This PMIC can efficiently provide up to 25A continuous with no additional discrete components or drivers. It supports USB-C and PPS, so it can offer high-speed data and power supply. The TPS65133DPDR is packaged in a 3x3 mm, 24-pin, lead-free QFN surface mount package.

The TPS65133DPDR is a voltage-mode constant frequency buck controller with a wide output range of 1.3V to 5V. It consists of a switch control circuit, an error amplifier, a compensation network, an output voltage control circuit and an internal clock circuit. Other features of the TPS65133DPDR include voltage monotonic start-up, undervoltage lockout, current limit and thermal shutdown protection.

When the TPS65133DPDR operates in phase shedding mode, it reduces the switching frequency when the current is above the specified threshold while maintaining the efficiency of conversion. This feature allows the TPS65133DPDR to reduce its operating temperature, making it ideal for applications that require high efficiency at a low operating temperature. It also supports low-noise transient control, which eliminates high-current spikes during conversion and reduces inrush current.

The TPS65133DPDR can be used in a variety of applications, such as mobile phones, personal digital assistants, digital cameras, and portable game consoles, where its high efficiency, low noise and low quiescent current make it a suitable choice for power management.

In conclusion, the TPS65133DPDR can provide power supply requirements for many digital systems, from mobile phones to digital cameras and game consoles. Its high efficiency, low noise and low quiescent current make it a suitable choice for power management, particularly for low-power applications. The TPS65133DPDR is a voltage-mode constant frequency buck controller with a wide output range of 1.3V to 5V and a phase-shedding feature to reduce its operating temperature.
