Description
LTC3605IUF#TRPBF is Linear Technology’s buck switching regulator (DC-DC converter) in a Pb-free, Tape-and-Reel package. It integrates the control circuitry and power switches to convert a higher input voltage to a stable lower output with high efficiency. The IUF suffix designates the package option and #TRPBF indicates Pb-free Tape & Reel packaging. The device supports voltage-mode or current-mode regulation, external compensation, adjustable output via feedback resistors, overcurrent/short-circuit protection, thermal shutdown, and soft-start. It’s suitable for portable and industrial power supplies requiring compact layout and minimal external components. For exact electrical specs—VIN range, VOUT range, switching frequency, synchronization, and protection details—consult the LTC3605 datasheet and product page.
Features
Here are the key features of LTC3605IUF#TRPBF:
- Synchronous buck regulator with integrated high-side and low-side MOSFETs
- Wide input range suitable for battery and low-voltage supplies (typical Li‑ion range)
- Adjustable output via external resistor network (0.8V up to a few volts)
- Fixed-frequency, current-mode PWM control for fast transient response
- High efficiency with low quiescent current (batTERY-powered suitability)
- Protections: overcurrent/short-circuit, thermal shutdown, UVLO
- Enable input and Power-Good signal for system reliability
- Soft-start and power-on reset; external compensation options
- Small-footprint package: IUF (QFN) with exposed pad; Pb-free; Tape & Reel (TRPBF)
Note: Exact voltage ranges and pin counts are in the datasheet.
