                                              Technology 150KHz,2A, PWM Step-Down DC/DC Converter
Description
The ACE150x series are monolithic IC designed for a step-down DC/DC converter, and own the ability of
driving 2A load without additional transistor. It saves board space.
The Internal compensation makes feedback control having 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 against over current operating of the output switch. If current limit
function occurs and VFB is down below 0.5V, the switching frequency will be reduced.
The ACE150x series operate at a switching frequency of 150KHz. 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
chips are available in a standard 8-lead SOP-8 package..
