Additional Details

The LTM4609 is a high efficiency switching mode buckboost power supply. Included in the package are the switching controller, power FETs and support components. Operating over an input voltage range of 4.5V to 36V, the LTM4609 supports an output voltage range of 0.8V to 34V, set by a resistor. This high efficiency design delivers up to 4A continuous current in boost mode (10A in buck mode). Only the inductor, sense resistor, bulk input and output capacitors are needed to finish the design.

The low profile package enables utilization of unused space on the bottom of PC boards for high density point of load regulation. The high switching frequency and current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The LTM4609 can be frequency synchronized with an external clock to reduce undesirable frequency harmonics.

Fault protection features include overvoltage and foldback current protection. The DC/DC μModule® regulator is offered in small 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. The LTM4609 is available with SnPb (BGA) or RoHS compliant terminal finish.

Product Detail

Demonstration circuit DC1477B features the LTM4609EV, the high voltage, high efficiency, high density switch mode buck-boost power module. The LTM4609EV regulates an output voltage above, below, or equal to the input voltage. DC1477B accepts an input voltage from 10V to 36V with a preset output voltage of 30V at up to 3A. Derating may be necessary for certain VIN, VOUT, and thermal conditions. An optional input π filter is added on the DC1477B to minimize the input ripple. The switching frequency may be synchronized to an external clock from 200kHz to 400kHz to reduce undesirable frequency harmonics and/or parallel multiple modules for even higher output current.
