The S-8337ACCB-T8T1G is a DC/DC switch controller, which is part of a Power Management IC (PMIC) family known as voltage regulators. It is designed to enable designers to implement a wide range of stable, cost effective and advanced voltage regulator configurations. With its low power consumption and small transistor footprint, the S-8337ACCB-T8T1G is ideal for designs where space and power efficiency are key considerations.

The S-8337ACCB-T8T1G is capable of controlling DC/DC buck, boost, flyback, forward, and SEPIC converters. It contains a PFC (Power Factor Correction) circuit capable of achieving up to 94% efficiency. The product can also support low-power applications, such as battery-backed products.

The S-8337ACCB-T8T1G is designed for a broad range of applications, such as servers and desktops, audio and video products, digital TVs, set-top boxes, and medical products. Additionally, it is suitable for a variety of power supply designs, including those with non-standby operation, modern standby operation, and compact designs.

The S-8337ACCB-T8T1G provides a high degree of flexibility, allowing a designer to adjust the target voltage and frequency quickly and easily. Its wide input voltage range and programmable soft start feature ensure reliable regulation and increased system protection. The product’s over-voltage protection, under-voltage protection and over-temperature protection work together to protect the system, while its 4-step constant off time current mode control architecture offers excellent line and load regulation, reducing the need for EMI filtering.

The S-8337ACCB-T8T1G features an internal oscillator and includes a shutdown pin, allowing it to enter a low-power standby mode. This functionality is especially useful for battery-backed applications, as it reduces unnecessary power consumption. The product also supports maximum power point tracking (MPPT) operation, providing better efficiency and power output for higher voltage input applications.

The S-8337ACCB-T8T1G uses a readback function for output voltage adjustment, which allows a designer to monitor and control the output voltage remotely. It also includes an output disable pin, which allows the output connection to be disconnected in cases where the system is not being used. This feature helps to reduce power losses, thereby improving system performance.

The working principle of the S-8337ACCB-T8T1G is based on pulse width modulation (PWM) and pulse frequency modulation (PFM). It uses a high-frequency oscillator and a comparator to control the output voltage. The oscillator determines the frequency of the pulses and the comparator senses the output voltage. Based on the readings, the switch is turned on or off accordingly, resulting in regulation of the output voltage. The PFM mode is used to reduce the switching frequency, resulting in lower power consumption and improved efficiency when the output load is low.

In addition to its voltage regulation capabilities, the S-8337ACCB-T8T1G also includes a power diagnostic feature that allows the system to detect and report various power supply issues. This includes over-voltage, under-voltage, and over-temperature conditions. This feature helps designers to efficiently monitor the power system, ensuring it is operating properly and providing maximum protection to the system.

The S-8337ACCB-T8T1G is an excellent choice for applications requiring reliable voltage regulation and efficiency, as well as advanced power supply diagnostics. It is simple to use, provides adjustable output voltage and soft start capabilities, and allows a designer to monitor and adjust the output voltage remotely. With its low power consumption and PFC support, the S-8337ACCB-T8T1G is a great choice for applications in a variety of power supply design scenarios.
