GENERAL DEscriptION
The ACT4060A is a current-mode step-down
DC/DC converter that provides up to 2A of output
current at 400kHz switching frequency. The device
utilizes Active-Semi’s proprietary high voltage
process for operation with input voltages up to 24V.
The ACT4060A provides fast transient response
and eases loop stabilization while providing
excellent line and load regulation. This device
features a very low ON-resistance power MOSFET
which provides peak operating efficiency up to 96%.
In shutdown mode, the ACT4060A consumes only
10μA of supply current.
This device also integrates protection features
including cycle-by-cycle current limit, thermal
shutdown and frequency fold-back at short circuit.
The ACT4060A is available in a SOP-8 package
and requires very few external devices for
operation
