7Semi DC-DC Buck Converter 7V -100V Input to 5V 1A Output - LM5164
7Semi DC-DC Buck Converter 7V -100V Input to 5V 1A Output - LM5164
This breakout board from 7Semi utilises the TI LM5164 synchronous buck converter IC to deliver a stable 5 V output at up to 1 A from an exceptionally wide input voltage range (7 V to 100 V). It is designed for rugged, industrial, and battery‑powered applications where a large voltage step‑down is required with high efficiency and minimal component count. The board integrates protection features, ultra‑low quiescent current, and enhanced EMI performance.
Technical Specification:
- IC: LM5164
- Input voltage range: 7 V to 100 V (typical support from 6 V to 100 V)
- Output voltage: 5 V fixed
- Maximum output current: 1 A
- Control mode: Constant‑On‑Time (COT) synchronous buck
- Minimum controllable on‑time: ~50 ns
- Quiescent current (no load): ~10.5 µA typical
- Shutdown current: ~3 µA typical
- Switching frequency: Up to ~1 MHz (programmable)
- Protections: input undervoltage lockout (UVLO), thermal shutdown, peak & valley current limit
- Operating temperature: –40 °C to +150 °C (junction)
- Efficiency: High efficiency even with large input‑to‑output differential
- EMI compliance: Optimised for low‑noise, meeting standards such as CISPR 25 Class 5
Features:
- Very wide input voltage range accommodates battery packs, industrial supplies, and high‑voltage rails
- Integrated high‑ and low‑side MOSFETs reduce external components
- Ultra‑low quiescent and shutdown current for efficient standby and sleep operation
- Programmable switching frequency up to 1 MHz allows compact external components
- Constant‑On‑Time architecture offers excellent line and load transient response
- Advanced protection features ensure safe operation under fault conditions
- Compact breakout board format for prototyping and embedded integration
- Suitable for high cell‑count battery packs or high‑voltage input systems
Applications:
- Industrial power supplies stepping down high DC link voltages to 5 V for logic or control circuits
- High‑cell‑count battery systems (e‑bikes, electric scooters, battery stacks)
- Embedded systems where the input supply can vary significantly above the output
- Automotive or transportation electronics requiring robust conversion from high bus voltages to 5 V
- IoT/edge devices connected to high‑voltage sources needing efficient regulation
- Communication equipment and control modules where a 5 V rail is derived from wide‑range input sources
