FEATUR
?? 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 R Ceramic Capacitors
?? SOP-8/EP (Exposed Pad) Packag
GENERAL DCRIPTION
The CX4070 is a current-mode step-down DC/DC converter that generat up to 3A output current at 400kHz switching frequency. The device utiliz Active-Semi’s proprietary ISOBCD30 procs 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 featur include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit.
The device also includ an internal soft start function to prevent overshoot.
The CX4070 is available in SOP-8/EP exposed pad package and requir very few external devic for operation.
APPLICATIONS
?? TFT LCD Monitors or Televisions and HDTV
?? Portable DVD Players
?? Car-Powered or Battery-Powered Equipment
?? Set- Box
?? Telecom Power Suppli
?? DSL and Cable Modems and Routers
