The SKY87609-11-578LF from Skyworks Solutions is a versatile 28V step-down DC-DC controller designed for applications requiring efficient power conversion. It operates over a wide input voltage range of 4.5 V to 28 V and can regulate output voltages as low as 0.9 V, while supplying up to 6 A of load current.
This controller features a fixed switching frequency of 450 kHz, enabling efficient step-down regulator designs. It includes an adjustable output voltage that can be set from 0.9 V to 80% of the input voltage via an external resistive voltage divider. The device incorporates internal soft-start to prevent excessive inrush current and offers protection features such as input under-voltage, over-current, and thermal overload protection.
The SKY87609-11-578LF is housed in a compact 12-pin TSOPJW package, measuring 2.85 mm x 3.00 mm, making it suitable for space-constrained designs. Its mounting type is surface mount.
Key electrical specifications include up to 97% efficiency and a shutdown current of less than 1 µA. The controller also offers optional low-side MOSFET driver capabilities and features like frequency control.
