AP1507
150KHz, 3A PWM BUCK DC/DC CONVERTER
Description
The AP1507 is a monolithic IC designed for a step-down DC/DC
converter and is capable of driving a 3A load without an external
transistor. Due to reducing the number of external components, the
board space can be saved easily. The external shutdown function
can be controlled by logic level and then come into standby mode.
The internal compensation makes the feedback control have good
line and load regulation without an external design. Regarding the
protected function, the thermal shutdown is to prevent over
temperature operating from damaging the device, and current limit is
against over current operating of the output switch. If the current limit
function occurred and V FB is down to 0.5V below, the switching
frequency will be reduced. The AP1507 series operates at a
switching frequency of 150KHz 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% on the oscillator frequency. The output
version included a fixed 3.3V, 5V, 12V, and an adjustable type.
AP1507 is available in a 5-lead TO-252 lead-free or green package.
