General Description
The AP1506 series are monolithic IC designed for a
step-down DC/DC co nverter, and ow n the ability of
driving a 3A load without external transistor. Due to
reducing the number of external comp onent, t he
board space c an b e sa ved ea sily. The external
shutdown function can b e co ntrolled b y lo gic l evel
and t hen come into st andby m ode. The in ternal
compensation makes fe edback control ha ve go od
line an d lo ad reg ulation wit hout ex ternal de sign.
Regarding pr otected fun ction, th ermal s hutdown is
to prevent over temperature operating from damage,
and current limit is to prevent over current operating
of the output swi tch. I f cur rent li mit f unction
occurred an d V FB is d own to 0.5V below, the
switching frequency will be reduced. The AP1506
series operate at a switching frequency of 150KHz
thus all owing smal ler size d f ilter co mponents t han
what would b e needed w ith lower fr equency
switching r egulators. Oth er fe atures in clude 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 fixed 3.3V, 5V, 12V, and an
adjustable type. The packages are available in a
standard 5-lead TO-220 package or a 5-lead
TO-263.
