Available at Mouser, Analog Devices Inc. LTM4655 Demonstration Circuit offers an easy method to measure and evaluate the LTM4655 Dual/Single Inverting μModule® Regulators. The LTM4655 is an EN55022B compliant 40V, dual 4A or single 8A step-down or 50W inverting DC/DC μModule Regulator. The ADI LTM4655 Demonstration Circuit has set switching frequencies of both channels at 1.2MHz. Suppose the output voltage collapses sufficiently due to an overload or short-circuit condition. In that case, the internal oscillator will fold back to one-fifth of the LTM4655’s programmed switching frequency, protecting the power switch from damage.
