Linear Technology LT1766/LT1766-5 Step-Down Switching Regulator Datasheet
The LT1766/LT1766-5 series from Linear Technology is a monolithic buck regulator that operates from a wide input range of 5.5 V to 60 V and provides a fixed 5 V output in the LT1766‑5 version. It features a constant 200 kHz switching frequency, 1.5 A peak switch current, and a shutdown current as low as 25 µA, making it suitable for battery‑powered and portable applications.
The device is offered in 16‑lead plastic TSSOP and SSOP packages with exposed‑pad options for improved thermal performance. Detailed electrical characteristics, pin functions, and typical performance graphs are provided to aid designers in implementing the regulator in a variety of power‑management designs.
