S-85S0AB09-I6T1U is a DC-DC switching regulator that can adjust the output voltage or current by switching or linear changing the duty cycle of the switch. It is mainly used in applications with positive, negative or adjustable output. It is commonly applied in switching mode power supplies (SMPS), power factor correction (PFC), and mobile device chargers.

The S-85S0AB09-I6T1U is manufactured by Vicor. It features a 36V input voltage range. It has a switching frequency of 460kHz and provides a non-synchronous PWM-type boost, buck, and buck-boost operation that is optimized for low-noise and high efficiency. It has a remote status monitoring of output voltage and temperature, and has a power-good flag and adaptive over-voltage protection capability.

The S-85S0AB09-I6T1U uses an internal control loop to adjust the switch duty cycle to maintain output voltage regulation. Its control loop includes an error amplifier, adjustor, an oscillator and switching regulation loop. Its main function is to control the output voltage of the power supply at a regulated level. The error amplifier receives the input voltage, compares it to a preset reference voltage, and converts it into an analog control signal. The bandgap reference adjusts this control signal to ensure accurate voltage regulation. The oscillator generates switching pulses which activate the power switch periodically. Finally, the once-regulated output voltage is sampled and the cycle repeats.

The S-85S0AB09-I6T1U is a good choice for DC-DC conversions due to its high efficiency and reliability. Its high efficiency ensures low power consumption of the device, and its low noise operation ensures that it does not interfere with other components in the system. It is an ideal choice for applications where space and power consumption are critical considerations.

In summary, the S-85S0AB09-I6T1U from Vicor is an excellent choice for DC-DC switching regulator applications. It features high efficiency, low power consumption, low noise operation and reliable performance over a wide temperature range. It is designed to operate on a 36V input voltage range and its adjustable PWM-type boost, buck and buck-boost operation provides excellent performance. It is suitable for a wide range of applications ranging from switching mode power supplies to power factor correction, and mobile device chargers.
