The CX4060 is a current-mode step-down
DC-DC converter that generates up to 2A
output current at 360kHz switching frequency.
The device utilizes advanced BCD process for
operation with input voltage up to 18V
consuming only 20µA in shutdown mode, the
CX4060 is highly efficient with peak efficiency
at 95% when in operation.
Protection features include cycle-by-cycle
current limit, thermal shutdown, and frequency
fold back at short circuit.
The CX4060 is available in SOP-8
package and requires very few external
devices for operation.
