The LT1766EGN-5#TR from Linear Technology is a robust step-down switching regulator designed for high-voltage applications. It accepts an input voltage from 5.5V to 60V and provides a fixed 5V output with up to 1.5A of current. The 200kHz fixed switching frequency balances efficiency with external component size. Packaged in a 16-pin SSOP, this IC is ideal for automotive, industrial, and telecom power supplies requiring wide input tolerance and reliable 5V delivery.
- Wide Input Voltage: 5.5V to 60V handles automotive load dumps and industrial 48V rails.
- High Efficiency: Internal 1.5A switch with low saturation voltage minimizes power loss.
- Fixed 200kHz Frequency: Simplifies EMI filtering and allows small inductors.
- Robust Protection: Built-in thermal shutdown and current limiting enhance system reliability.
