AP1506
150KHz, 3A PWM BUCK DC/DC CONVERTER
Description
The AP1506 series are monolithic IC designed for a step-
down DC/DC converter, and own the ability of driving a 3A
load without 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 feedback control have good line and
load regulation without external design. Regarding protected
function, thermal shutdown is to prevent over temperature

operating from damage, and current limit is to prevent over
current operating of the output switch. If current limit function
occurred and V FB is down to 0.5V below, the switching
frequency will be reduced. The AP1506 series operate 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 fixed 3.3V,
5V, 12V, and an adjustable type. The packages are available
in a standard 5-lead TO263 and TO220.
