The ON Semiconductor NCP81147MNTXG is a precise low voltage synchronous buck controller designed for high efficiency power regulation. It features a wide input voltage range from 4.5V to 13.2V and supports output voltages from 0.8V to 3.3V, with a maximum output of 5V when using a 12V VCC.
Key electrical specifications include a 100kHz to 1MHz adjustable oscillator frequency, a 95% maximum duty cycle, and synchronous rectification for improved efficiency. The controller incorporates features such as internal soft-start, overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown for robust operation. It also includes automatic power saving mode for maximizing efficiency during light load conditions.
The device is housed in a 16-QFN (3x3) package with surface mount mounting type. The operating temperature range is -40°C to 85°C (TA). This controller is suitable for applications in desktop and server systems requiring accurately regulated power with low switching loss.
This buck controller offers a 0.5% internal voltage accuracy and a 0.8V voltage reference. It supports chip enable through the OSC pin and features a sync function. The integrated MOSFET drivers and boost diode simplify external component requirements.
