Description

The LTC7801EFE#TRPBF is Linear Technology (Analog Devices) dual high-voltage buck controller. It provides two independent current‑mode controller channels that drive external N‑channel MOSFETs to generate two regulated DC outputs from a high input voltage (typical up to ~60V). Key features usually include adjustable switching frequency, soft-start, enable/disable, current limit, overcurrent protection, thermal shutdown, and undervoltage lockout. It is a controller device (no MOSFETs built in), so you pair it with external FETs, inductors, and feedback resistors per your topology.
Suffix meaning:
- EFE: device variant/package/temperature grade.
- #TRPBF: Pb‑free, Tape & Reel packaging.
For exact electrical specs, pinout, and recommended topologies, refer to the LTC7801 datasheet and application notes.

Features

Here are the key features of LTC7801EFE#TRPBF (datasheet-based overview, compact and concise):
- High-voltage buck regulator controller designed to drive external N-channel MOSFETs
- Current-mode control for fast transient response and good regulation
- Programmable switching frequency
- Soft-start to limit inrush and output overshoot
- Cycle-by-cycle current limit with overcurrent protection
- Overvoltage protection and undervoltage lockout
- Thermal shutdown protection
- Enable input for controlled startup/shutdown
- Remote sense/feedback capability for accurate output regulation
- Fault reporting/flags for protection events
- Suitable for buck power supplies with external power MOSFETs and rectifier
- Package: LTC7801EFE in TRPBF (Tape-and-Reel) packaging
Note: The part number suffix (#TRPBF) denotes tape-and-reel packaging; EFE indicates the temperature grade/options. Always refer to the latest datasheet for exact electrical specifications and recommended external components.

Package

16-pin plastic TSSOP package; Pb-free; Tape & Reel (TRPBF) packaging.

Pinout

- Pin count: 16 pins (16-pin package, e.g., TSSOP-16).
- Function: High‑voltage buck switching regulator controller. Provides PWM control, reference/error amplifier, and protective features (UVLO, current limit/overcurrent, thermal) for driving external MOSFETs in DC‑DC converters.

Manufacturer
