DC2899A

DC2899A is a LTM4655 low EMI dual 13V to 28VIN, -12V/2.2AOUT negative µModule regulator demonstration board. Demonstration circuit 2899A is a dual inverting DC/DC converter with a 13V to 28V input voltage range, two 12V outputs at up to 2.5A each featuring the LTM®4655. The LTM4655 is an EN55022B compliant 40V, dual 4A or single 8A step-down or 50W inverting DC/DC µModule® regulator. The switching frequencies of both channels are set at 1.2MHz on DC2899A. If the output voltage collapses sufficiently due to an overload or short-circuit condition, the internal oscillator will foldback to one-fifth of the LTM4655’s programmed switching frequency, protecting the power switch from damage.

• SSFM jumper for spread spectrum options
• CLKIN inputs for external sync
• PGOOD signals for each output
• 88% efficiency at VIN = 28V, IOUT = 2.5A, TA = 25°C
