/a>led” title=”led”>led” title=”led”>led LTM4607 modules. The demo circuit can deliver up to 10A of output current for two paralleled modules (DC1601B-A), 15A for three paralleled modules ( DC1601B-B) and up to 20A for four paralleled modules (DC1601B-C). The DC1601B demonstrates that paralleling modules is easy and reliable.
The output voltage for the board is 12V. The rated load current per module is 5A in boost mode, however current derating may be necessary under certain VIN, VOUT, frequency, and thermal conditions. An onboard external clock is provided for synchronization and interleaving of L, LT, LTC, LTM, Linear Technology, PolyPhase and the Linear logo are registered trademarks of Linear Technology Corporation.

phases to minimize input and output ripple. An internal phase-locked loop allows the LTM4607 to be synchronized to an external clock within the range of 200kHz to 400kHz. The LTM4607 default switching frequency on the DC1601B is set to 300kHz through the onboard LTC6902 clock generator which interleaves the paralleled phases.
The frequency and phase separation set by the LTC6902 are resistor programmable.
These features, including the availability of the LTM4607 in a compact thermally enhanced 15mmx15mmx2.8mm LGA package make the demonstration circuit ideal for use in high density point of load regulation applications.
