ABLIC Inc. Voltage Regulators - DC DC Switching Regulators S-8591AA-A6T8U7

The S-8591AA-A6T8U7 is a synchronous step-down switching regulator designed for high efficiency and compact applications. It operates with an input voltage range of 4.0 V to 18.0 V and can deliver an output current of up to 600 mA. The output voltage is externally adjustable from 1.0 V to 12.0 V, with a feedback pin voltage accuracy of ¬±1.5%. This regulator features PWM/ PFM switching control, allowing it to maintain high efficiency under varying load conditions, achieving an efficiency of up to 91%. Key protective features include overcurrent protection (typical 1.2 A), thermal shutdown (typical 170¬8C), and short-circuit protection with hiccup and latch control options. The device supports a wide operating temperature range from -40¬8C to +85¬8C and is compatible with ceramic capacitors for input and output. It is available in compact packages suitable for high-density mounting, including HSNT-6(2025), which contributes to the miniaturization of electronic equipment.
