IC Introduction
KP1500
150Khz, 3A PWM Buck Switching Regulator
General Description
The KP1500 series are monolithic integrated
circuits that provide all the active functions for a
step-down DC/DC converter, capable of driving a
3A load without additional transistor component.
Requiring a minimum number of external
component, the board space can be saved easily.
The external shutdown function can be controlled
by TTL 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 against
over current operating of the output switch. The
KP1500 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 fixed 3.3V,
5V, 12V, and an adjustable type. The packages are
available in a standard 5-lead TO-220(T) package
and a 5-lead TO-263(U).
