The AP1512/A is a monolithic IC designed for use as a
step-down DC/DC converter with the ability of driving a 2A (3A for
AP1512A) load without additional transistor components. The
board space is reduced since AP1512/A requires few external
components. The external shutdown function is controlled by
logic level and can be put into standby mode. The internal
compensation ensures feedback control has good line and load
regulation without external design. Both an integrated Thermal
shutdown and Current Limit function are provided to prevent
damage from exceeding temperature operation and against
exceeding the current operating of the output switch. The
AP1512/A operates at a switching frequency of 50KHz thus
allowing smaller sized filter components than what would be
needed with lower frequency switching regulators. Other features
include a guaranteed +4% tolerance on output voltage under
specified input voltage and output load conditions, and +15%
tolerance on the oscillator frequency. The AP1512/A offers fixed
output voltages of 3.3V, 5V, 12V, plus Adjustable. The package is
available in a standard 5-lead TO263 package.
