Special purpose voltage regulators are an essential part of the power management solution for many industrial, consumer electronics and other applications. The S-1701A5043-U5T1G from STMicroelectronics, is an integrated special purpose controller providing all key features and features for optimized, low power and low cost power supply designs.
The S-1701A5043-U5T1G is a low-voltage, 3-phase synchronous buck controller for high-performance, low-noise power supply designs. This special purpose controller supports simulating start-up without a target voltage to minimize startup current, which is a critical parameter when space or temperature is limited. In addition, the controller allows users to reduce their power consumption when powering their system in low performance or idle mode.
The S-1701A5043-U5T1G is designed to reduce power losses and maximize energy efficiency by automatically adjusting each channel’s operating frequency based on load conditions. This feature helps keep the power IC cooler and makes the system quieter when running at lower loads. The embedded current sensing capability also helps maintain stability by regulating current over the cycle and active power factor correction (PFC) helps minimize system losses.
The S-1701A5043-U5T1G includes two dedicated PWM controllers for the buck channels, which operate independently and ensures that the controller can efficiently manage different loads. This device also supports a wide range of input voltage, including 3V to 17V for 12V systems and 0.6V to 17V for 24V systems. To prevent possible thermal overload interruptions, the on-chip overtemperature protection keeps the device at a safe operating temperature.
The S-1701A5043-U5T1G is suitable for use in systems ranging from cellphones, tablets and ultrabooks to industrial control and automation systems and is an ideal choice for a wide range of low-voltage, low-noise, energy efficient power supplies. This special purpose voltage regulator is an excellent choice for applications requiring reliable, energy-efficient and low-noise power supplies.
The S-1701A5043-U5T1G provides additional features and benefits that make it ideal for a wide range of applications. It offers precise control over multiple parameters including input and output voltages, current and PWM frequency, as well as spread spectrum modulation control, which helps to reduce electromagnetic interference (EMI). The integrated pre-bias start-up circuitry helps simplify start-up, and pulse-width modulation (PWM) frequency synchronization of the two controllers helps avoid instabilities caused by the interference between multiple channels. It also provides soft-start and fast-transition capabilities to reduce in-rush currents and minimize noise generated during power-up.
In sum, the S-1701A5043-U5T1G from STMicroelectronics is a low-voltage, 3-phase synchronous buck controller that is suitable for a wide range of applications. It is designed to reduce power losses and maximize energy efficiency by adjusting each channel’s operating frequency depending on load conditions, and offers precise control to ensure low-noise, energy-efficient power supplies. This special purpose voltage regulator is an excellent choice for applications requiring reliable, energy-efficient and low-noise power supplies.
