Alpha & Omega Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators AOZ1905FIL

The AOZ1905FIL is a high-performance step-up DC-DC switching regulator designed for applications requiring adjustable output voltage up to 24V. It operates within a 2.7V to 5.5V input voltage range and features a constant switching frequency of either 600kHz or 1.2MHz, selectable via a frequency select pin. The device incorporates internal MOSFETs, current-mode control for improved transient response, and essential protection features including input under-voltage lockout, cycle-by-cycle current limit, thermal shutdown, and programmable soft-start. This regulator is available in a compact 3mm x 3mm DFN-10 package and an MSOP-8 package, both rated for an operating temperature range of -40¬8C to +85¬8C. It is suitable for various applications such as LCD TVs, monitors, notebook displays, and handheld devices. The AOZ1905FIL is compliant with RoHS standards and is categorized as a Green Product, indicating reduced levels of halogens.
