The AS1917S-T is an adjustable step-down converter made by ams. It is a member of their AS1800 series, and is designed to provide a stable, low-ripple output voltage from a wide input range, over a wide operating temperature range. The device features an adjustable output voltage range from 0.8 V to 2.5 V, a high efficiency of 95%, 1.5 A switching current limit and an operating frequency of 1.2 MHz. It is fully protected with short circuit protection and it features thermal shutdown. The device is housed in a tiny ODFN-6 package making it ideal for space constrained designs.
