PMIC is an abbreviation for Power Management Integrated Circuit and is used in almost all electronic gadgets such as mobile phones, computers and other portable and handheld devices. The PMIC is responsible for taking care of the power supply of the device, managing and monitoring the internal systems, and ensuring the device runs reliably and efficiently.

UCD3138064RMHR is a PMIC designed and manufactured by TI. It is a low cost, low power “smart” power supply controller and monitor with an integrated frequency and duty cycle controller. It is specifically tailored to meet the power needs of consumer electronic and communication appliances applications, including embedded power supplies (EPS); desktop, laptop and mobile computers; tablet PCs; printers; and digital televisions (DTVs). The UCD3138064RMHR is a single-chip, 8L-DFN package solution with a 6 V to 30 V input range, maximum 12.5 A output current limitation, and 4 V to 16 V MCU and DSP standby power supply.

The UCD3138064RMHR application field focuses on consumer electronic devices that are limited on space, thin, and require a low-cost power solution. This includes digital cameras, consumer power supplies, consumer computing platforms (desktop, laptop, gaming systems, and tablets), LED lighting controls, consumer appliances, consumer audio/video systems, consumer electronic healthcare tools, consumer USB-type peripherals, consumer audio/video processing systems, consumer multimedia systems, consumer health/fitness monitors, consumer navigational systems, consumer medical devices, and portable consumer electronic devices.

The general working principle of UCD3138064RMHR is to convert the input power to the output power with as low loss and high efficiency as possible. An effective way to do this is through the use of a buck-boost converter. The UCD3138064RMHR utilizes TI\'s advanced synchronous buck-boost converter technology for its power delivery stages. This enables low input voltage, which allows for a minimal impact on the device’s input source’s life and the device’s temperature.

The UCD3138064RMHR integrates an advanced battery protection system to provide protection against over / under voltage, over / under current and total discharged capacity conditions. This protection system is further supplemented by multiple output voltage switching that facilitates regulation requirements of different loads. In addition, the UCD3138064RMHR also provides a deep sleep power mode to minimize power consumption in battery-powered applications.

In order to maintain system accuracy, UCD3138064RMHR utilizes an average on-time control, which controls the current flow through the external switch. An internal system voltage detector generates a proportional output voltage, which is then connected to the average on-time controller to adjust the external switch’s current so that it always remains within the specified range. This ensures that the output voltage remains accurate even with variations in the input voltage and the load current.

The UCD3138064RMHR provides a Dual phase power supply design. This allows for the integration of two external power sources and allows for a wider range of input voltages. Additionally, this dual-phase design helps reduce noise and ripple, and improves the overall efficiency of the power supply.

Overall, the UCD3138064RMHR power management integrated circuit is an excellent choice for consumer electronics applications that require increased levels of power efficiency and flexibility. It combines low power, high efficiency, and accuracy in a single-chip solution, making it a great solution for today\'s consumer electronics.
