S-8338ACBC-P8T1G Application Field and Working Principle
S-8338ACBC-P8T1G is a DC/DC switching controller manufactured by Renesas Electronics. This device is a single-channel, voltage mode, step-down switching regulator with an internal power switch, suitable for power supply design.
The S-8338ACBC-P8T1G is categorized as a PMIC (Power Management Integrated Circuit) which falls under the Voltage Regulators category, and more specifically under the DC/DC Switching Controllers. It provides several advanced features, making it suitable for a wide range of applications, incluing automotive, home appliances, computer, communication equipment and industrial systems.
The features of the S-8338ACBC-P8T1G include:
- Wide input voltage range (4.5V to 40V)
- High efficiency up to 96%
- Integrated power switches capable of delivering up to 4A continuous current
- Soft start ramp current limiting
- Voltage regulation accuracy of 0.8%
- Integrated over temperature protection
The principle of operation of this switching controller is based on a topology which consists of an internal power MOSFET, driver, and controller. The device achieves a high efficiency by exploiting a synchronous rectification technique, which employs both a low-side and a high-side power MOSFET. The switching frequency is adjustable between 200 kHz and 600 kHz to optimize efficiency for various applications. The switching frequency can also be synchronized to an external clock source.
The device is controlled by a voltage-mode control system based on peak current mode control. The voltage-mode control system sets the power switch on and off times to regulate the output voltage and adjust the dynamic response of the device. The PWM (Pulse Width Modulation) signal that sets the on/off ratio is proportional to the output feedback voltage. The device also features a soft start ramp current limit and supports an external current limit setting.
The S-8338ACBC-P8T1G is suitable for a diverse range of applications including notebook computers, automotive power supplies and industrial power systems. It can be used in applications such as adjustable power supply systems, digital switching supplies, or battery charger power sources.
