现货热销 ETA3707CSI 钰泰降压开关稳压器IC

　　DESCRIPTION

　　The ETA3707/A is a high-efficiency,DC-to-DC step- down switching regulator that features360nA ultra-low quiescent current. ETA3707 can provide output voltages from 1.2V to 3.3V, which is capable of delivering up to 1A of output current. ETA3707A can provide output voltages from 0.7V to 3.1V,which is capable of delivering up to 500mA of output current.

　　ETA3707/A adopts an adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load. During light load,ETA3707/A goes into a PFM mode that saves switching loss to achieve high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load. The interal soft-start control circuitry reduces inrush current. Over current and temperature protection improve design reliability.
