S-8337AAFA-P8T1G is a DC/DC an integrated switch controller from Sanken Electric Co., Ltd., which provides a variety of features that make it suitable for popular DC/DC conversion topologies like flyback and step-down (buck) converters. The device can be used in wide input voltage range and automotive applications with wide temperature range.

Application field

S-8337AAFA-P8T1G is programmed with standard software and provides either shutdown output or low voltage reset detection in response to an over-voltage condition. Users can also program various control parameters as well as the critical switching functions and operation mode via the integrated EEPROM. The adjustable soft start feature allows the maximum peak current limit, while the high transient response time and frequency jittering enable stable operation under difficult load conditions. Additionally, the built-in internal compensation scheme further maximizes the stability and performance of the switching converter. The integrated N-MOSFET driver is capable of driving the external switch at high current levels.

Working principle

S-8337AAFA-P8T1G is primarily used as a DC/DC switching controller to regulate and manage the power flows between the input and output sections. It supports a wide operating temperature range and can tolerate large changes in the input voltage due to power spikes or transient conditions. By using two integrated comparators, it accurately monitors the voltage at both the input and output terminals, and quickly responds to changes in the input or output voltage. The device provides over-voltage, under-voltage, and soft start features with the help of its integrated fuse. The over-voltage feature enables the device to shut down the output in response to an over-voltage condition while the under-voltage protection shuts down the output if the input voltage is below the set voltage level. The soft start feature by S-8337AAFA-P8T1G helps reduce inrush current issue at initial startup which helps prevent damage to attached load. Additionally, its frequency jittering and high transient response time ensures a stable operation under difficult load conditions.
