Skyworks SKY87609-11-578LF

降压降压4.5V ~ 28V

Overview

The SKY87609-11-578LF is a step-down DC-DC controller that operates over a wide 4.5 V to 28 V input voltage range and regulates output voltage as low as 0.9 V while supplying up to 6 A to the output. The 450 kHz switching frequency allows an efficient step-down regulator design.The SKY87609-11-578LF uses an adjustable output voltage that can be set from 0.9 V to 80% of the input voltage by an external resistive voltage divider. Internal soft-start prevents excessive inrush current without requiring an external capacitor.The SKY87609-11-578LF includes input under-voltage and over-current protection to prevent damage in the event of a fault. Thermal overload protection prevents damage to the SKY87609-11-578LF or circuit board when operating beyond its thermal capability.The SKY87609-11-578LF is available in a small 12-pin 2.85 mm × 3.00 mm TSOPJW package.
