尚亿微电子低价供应降压IC CX4070，工作电压:4.5~30V输出功率（电压）:可调输出电流:3A工作频率:400KHz封装形式:SOP-8
FEATURES
?? 3A Output Current
?? Up to 95% Efficiency
?? 4.5V to 30V Input Range
?? 6μA Shutdown Supply Current
?? 400kHz Switching Frequency
?? Adjustable Output Voltage
?? Cycle-by-Cycle Current Limit Protection
?? Thermal Shutdown Protection
?? Internal Soft Start Function
?? Frequency Fold Back at Short Circuit
?? Stability with Wide Range of Capacitors,
Including Low ESR Ceramic Capacitors
?? SOP-8/EP (Exposed Pad) Packag
GENERAL DESCRIPTION
The CX4070 is a current-mode step-down DC/DC converter that generates up to 3A output current at 400kHz switching frequency. The device utilizes Active-Semi’s proprietary ISOBCD30 process for operation with input voltage up to 30V.
Consuming only 6μA in shutdown mode, the CX4070 is highly efficient with peak efficiency at95% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit.
The device also includes an internal soft start function to prevent overshoot.
The CX4070 is available in SOP-8/EP exposed pad package and requires very few external devices for operation.
APPLICATIONS
?? TFT LCD Monitors or Televisions and HDTV
?? Portable DVD Players
?? Car-Powered or Battery-Powered Equipment
?? Set-Top Boxes
?? Telecom Power Supplies
?? DSL and Cable Modems and Routers
