CoolConverter™

Galaxy’s proprietary CoolConverter™ provides:

•Patent Pending single-stage power conversion

architecture, control, and magnetic design allow

unprecedented power density and efficiency in an isolated

power supply.

• An advanced microcontroller reduces parts count while

adding features, performance, and flexibility in the design.

Protection and Control

Valid Input Voltage Range:

The converter measures the input voltage and will not

allow operation outside of the input voltage

specification. As shown by the graphs, hysteresis is

added to both the high and low voltage to prevent the

converter from turning on and off repeatedly when the

voltage is held near either voltage extreme. At low line

this assures the maximum input current is not exceeded;

at high line this assures the semiconductor devices in

the converter are not damaged by excessive voltage

stress.

ON/OFF Logic Option:

The ON/OFF control logic can be either Negative

(standard) or Positive to enable the converter. For

Negative logic, the ON/OFF pin is brought below 1.0 V

with respect to the –INPUT pin to enable the converter.

For Positive logic, the ON/OFF pin is brought to greater

than 4.0 V with respect to the –INPUT pin. To request

the Positive logic version, add the suffix (P) to the

standard part number. The positive version has a built-

in pull up resistor of approximately 100 k

Ω.
