概要
Description
LT8601EUJ#TRPBF is the Pb-free, Tape & Reel version of Analog Devices’ LT8601 wide-input DC-DC converter/controller (from Linear Technology). The EUJ suffix denotes the package type, and TRPBF indicates Tape & Reel Pb-free packaging.
What it is:
- A high-voltage, wide-input-range DC-DC regulator/controller designed to regulate to a user-set output using an external power stage (inductor, diode or synchronous MOSFET).
- Capable of buck-boost operation, making it suitable for automotive and other harsh-input applications.
Key points:
- Requires external components for the inductor, feedback divider, and protection networks.
- Provides protections such as undervoltage lockout, overcurrent/short-circuit protection, and thermal shutdown.
- Used to implement a stable output across varying input conditions with high efficiency.
For exact electrical specs, pinout, typical application circuits, and layout guidelines, see the LT8601 datasheet and the LT8601EUJ#TRPBF packaging notes on Analog Devices’ or distributors’ sites.

Features
Here are the key features of LT8601EUJ#TRPBF (typical for LT8601 family):
- Wide input voltage range suitable for automotive/industrial use (high voltage up to around 60V)
- Buck-boost DC-DC converter capable of regulating output across large input swings
- Synchronous operation with internal switching elements for high efficiency
- External feedback network to set adjustable output voltage
- PWM control with stable fixed frequency operation
- Built-in protections: overcurrent/short-circuit, overtemperature, undervoltage/overvoltage
- Enable pin with proper startup sequencing and undervoltage lockout
- Soft-start to limit inrush and prevent output overshoot
- Low quiescent current in sleep/idle modes
- Packaging: LT8601 in EUJ package with TRPBF (tape-and-reel) variant
Note: For exact electrical specs (range, efficiency, switch frequency, maximum output current, and precise protection behavior), please consult the latest datasheet.
