? GENERAL DESCRIPTION
The AX3902 is a high efficiency, 2A current mode synchronous step down DC/DC converter with a wide input voltage range from 4.5V to 18V. The device integrates high side and low si de MOSFETs to achieve high efficiency conversion.
The current mode architecture supports fast transient response and internal compensation. The AX3902 provides complete fault protection including input under voltage lockout output short circuit protec tion, over current protection, and thermal shutdown. The switching frequency is internally set at 500kHz. AX3902 have different operation modes:
AX3902 is automatic PSM/PWM mode
To improve the light load efficiency, AX3902 has proprietary light load p ower saving mode (PSM) to minimize the switching loss by reducing the switching frequency.
The AX3902 is available in the SOT-23-6L package.
? FEATURES
- Input Voltage Supply Range from 4.5V to 18V
- +/-2% 0.8V Feedback Voltage Accuracy
