AP1506

150KHz, 3A PWM BUCK DC/DC CONVERTER

Description

Pin Assignments

( Top View )

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_FBis 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.
