DC1041A-A

DC1041A-A demonstration circuit features the LTM®4601EV, a 12A high efficiency, high density switch mode step-down converter. The input voltage ranges from 4.5V to 20V. The output voltage is jumper selectable for popular voltages from 0.6V to 5V. The PLLIN pin supports synchronizing the μModule® regulator to an external clock. The TRACK/SS pin allows the user to program output ramp-up and ramp-down rates which may coincidentally or ratiometrically track with another supply’s output if desired. Output voltage margining of ±5% from the nominal value is available via the margin control pins MARG0 and MARG1.

• Output voltage VOUT: 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V at jumper selectable (open for 0.6V)
• 850kHz default operating frequency
• External synchronous clock frequency range from 600kHz to 1000kHz
• 83%, efficiency at VIN = 12V, VOUT = 1.5V, IOUT = 12A
