Description
LT7182SRV#PBF is the Pb-free (RoHS) variant of Linear Technology/Analog Devices’ LT7182, an 8-pin high-side switch/load-switch device. It provides a protected, current-limited feed to a downstream load, with enable and fault/status reporting. The “SRV” portion denotes the package variant, while “#PBF” confirms Pb-free manufacturing. For exact electrical specs (voltage/current range, protection features, pinout), refer to the LT7182 datasheet and product page. Typical use cases include protecting and power-switching rails in automotive and other dc power designs.
Features
I don’t have the exact datasheet in this chat, but LT7182SRV#PBF is a Linear Technology part that’s typically described as a dual, high-efficiency, synchronous buck regulator/controller. Expected features include:
- Dual synchronous buck regulators with integrated high-side MOSFETs
- Current-mode control with fixed/frequency PWM
- Independent feedback/outputs for two channels
- Adjustable output voltages via external feedback resistors
- Soft-start and programmable undervoltage lockout
- Overcurrent/short‑circuit protection and thermal shutdown
- Overvoltage protection and fault/power-good indicators
- Enable pins for each channel (and/or combined enable)
- RoHS-compliant package (SRV), suitable for compact designs
Note: exact specs (input range, switching frequency, pinout, protection thresholds) vary by package/revision—please share the datasheet or confirm you want me to pull the precise details.
