4.5~30VDC-DC 电源芯片
The EUP3458 is current mode， step-down switching regulator capable of driving 1.2A conTInuous load with excellent line and load regulaTIon. The EUP3458 can operate with an input voltage range from 4.5V to 30V and the output can be externally set from 0.8V to 15V with a resistor divider. Fault protecTIon includes cycle-by-cycle current limiTIng and thermal shutdown. In shutdown mode the regulator draws 1µA of supply current. Internal soft-start minimizes the inrush current and the output overshoot. The EUP3458 is available in SOT23-6 and TSOT23-6 packages.
