The ACT8700QLEGA-T is a specialized power management solution from Advanced CMOS Technology (ACT). It is an integrated power management integrated circuit (PMIC) that provides efficient, low-cost and reliable power conversion and control for systems that require high voltage regulation. It is designed for use in applications such as set-top boxes, digital TVs, and embedded systems.

The ACT8700QLEGA-T integrated PMIC has a wide range of voltage-regulating capabilities and provides up to four channels of high accuracy voltage regulation. It includes two switching DC-DC converters, two linear regulators, and an integrated load-switch with enable/disable control. The output voltage can be programmed from 0.8 to 7 volts with a high accuracy of 5 percent. Also integrated are two adjustable low dropout (LDO) regulators with enable/disable control.

The main features of the ACT8700QLEGA-T that makes it an attractive choice for powering embedded systems are its low power consumption, high power efficiency, and small form-factor package. Its maximum power dissipation is just 667mW and its quiescent current is only 10µA. Its switching frequency can be programmed from 200KHz-2MHz, providing the flexibility to optimize system efficiency over a wide range of input voltages and loads. Compared to discrete solutions, it provides up to 94 percent power efficiency, and its small form-factor package size reduces the overall solution size significantly.

The ACT8700QLEGA-T works by using a Pulse Width Modulation (PWM) technique to control the output voltage. PWM is a widely used method of controlling the output voltage of a power supply. It works by rapidly switching the output voltage between a certain high and low level, thus creating a pulse whose width is proportional to the average output voltage. This technique is highly efficient and is used in many products because it allows for a much higher power conversion ratio than other forms of power conversion.

The ACT8700QLEGA-T is ideal for applications that require efficient, low-cost and reliable power conversion and control. It is also suitable for systems that require a high level of accuracy in their voltage regulation, such as embedded systems. It has a small form-factor package, low power consumption, and high power efficiency, making it an attractive solution for powering embedded systems. With its wide range of voltage-regulating capabilities and PWM control, the ACT8700QLEGA-T is a powerful and reliable power management solution.
