OM71911 is a synchronous buck converter that supports a wide input voltage range of 6-100V, which can effectively meet the application requirements of external surge suppression. The device can provide a maximum continuous load current of 1A and supports setting the switching frequency through an external resistor.
The device achieves high-efficiency operation through integrating high-side and low-side MOS, and uses constant on-time (COT) to achieve fast line response and load response without the need for external compensation devices.
The device monitors output voltage and fault reporting through the open-drain output PGOOD pin (Optional).
The OM71911 has comprehensive protection functions such as current limiting, input undervoltage lockout, and thermal shutdown.
The OM71911 uses an eSOP8L package with a rated junction temperature range of -40°C to 125°C.
