概要
Description
Key points:
- Current-mode PWM controller with adjustable switching frequency, soft-start, and enable.
- Wide input range and protective features (overcurrent/short-circuit, undervoltage lockout, overvoltage, thermal shutdown).
- Gate-drive outputs for high- and low-side FETs; suitable for multiphase interleaving for high-current designs.
Typical uses include voltage-regulator modules (VRMs) and point-of-load regulators in processors, telecom, and other power-management applications.
For exact electrical specs, programming options, and reference designs, consult the TI LM5176RHFR datasheet.
Equivalent
- Within TI: other LM5176 family parts in different packages (same device, different packaging).
- From other vendors: Analog Devices LTC3897/LTC3899 or LTC385x multiphase buck controllers (similar function).
Note: always verify input range, voltage/current ratings, phase count, and enable/FSYNC features to ensure proper replacement.
Features
- Wide input range: 6 V to 60 V support
- Synchronous buck-boost regulator with integrated high- and low-side MOSFETs
- Current-mode control with programmable peak current limit
- Adjustable output voltage via resistor divider; remote sense available
- Programmable switching frequency
- Enable pin with undervoltage lockout
- Soft-start and power-good monitoring
- Overcurrent/short-circuit protection with hiccup
- Overvoltage and undervoltage protection
- Overtemperature protection with automatic restart
- Fault/status pins for health monitoring
- Tape-and-Reel packaging (RHFR), RoHS-compliant
Pinout
- Function: TI LM5176RHFR is a high‑voltage DC‑DC controller (dual/dual‑phase buck-boost style) that drives external MOSFETs. It provides PWM control, two feedback paths, current sensing, enable/soft‑start, oscillator frequency set (RT), and protection features (overcurrent/overvoltage).
Manufacturer
What kind of company: An American multinational semiconductor company that designs and manufactures a wide range of integrated circuits, especially analog, power-management, and embedded processing products.
Application
- Automotive electronics (wide Vin with transients)
- Industrial power supplies and motor-drive front ends
- Telecom/datacom power rails and post-regulation
