PKM7116ZWPI

The PKM7116ZWPI is a high-performance, low-power DC-DC buck converter from ROHM Semiconductor. Designed for efficient voltage regulation, it features:
- Input Voltage Range: 4.5V to 18V
- Output Voltage: Adjustable (0.8V to 15V)
- Output Current: Up to 1A
- High Efficiency (up to 95%)
- Low Quiescent Current (40µA)
- Built-in Protection: Overcurrent, thermal shutdown, and undervoltage lockout (UVLO)
Ideal for IoT devices, industrial systems, and battery-powered applications, the PKM7116ZWPI offers compact size (SOT-23-5 package) and stable performance under varying loads. Its PWM control ensures precise voltage regulation with minimal ripple.
