科瑞芯代理 ETA3423DCG 钰泰1A降压转换器IC

　　DESCRIPTION

　　The ETA3423 is a high-efficiency,DC-to-DC step- down switching regulator, capable of delivering up to 1A of output current. The devices operate from an input voltage range of 2.6V to 6.5V and provide output voltages from 0.6V to VIN,making the ETA3423 ideal for low voltage power conversions. Running at a fixed frequency of 3MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies.Other external components, such as ceramic input and output caps, can also be small due to higher switching frequency, while maintaining exceptional low noise output voltages. Internal soft-start control circuitry reduces inrush current.Short-circuit and thermal-overload protection improves design reliability.
