The S-8338ACIC-T8T1G is a DC DC switching controller manufactured by Renesas Electronics. The device is part of the Power Management IC (PMIC) family and more specifically the Voltage Regulators group. The device is capable of generating an output voltage from a wide input supply of 4.9V to 40V and provides constant output current up to 2A. This makes it suitable for a variety of applications such as LED backlighting, industrial control applications, automotive systems and consumer applications.

In terms of its working principle, the device combines an analog current-mode buck converter with digital startup control circuit, allowing the device to be used in both continuous and step-down mode. It features programmable soft-start time and current limit, external PWM control to manage the output frequency, output over voltage protection and an integrated main switch with a current sense resistor. The device also has input under voltage lockout and CMOS compatible control logic for low power consumption.

The S-8338ACIC-T8T1G provides excellent efficiency across a wide range of applications such as automotive infotainment systems, LED backlight solutions and industrial applications due to its high frequency operation and low on-resistance of the power MOSFET. Furthermore, by having the ability to program the soft-start time, the device can be used to reduce the inrush current for applications that require high current inrush to start.

With excellent efficiency, a wide input voltage range, advanced control features and high current drive capability, the S-8338ACIC-T8T1G is a highly advanced switching controller suitable for a range of applications. It has features such as an integrated main switch with current-sense resistor and advanced CMOS compatible control logic which make it ideal for managing the power supply in automotive systems, consumer products, industrial equipment and other power sensitive applications.
