description

LTM^®The 4606 is a full EN55022 Class B certified high voltage, 6A switch-mode DC/DC power supply. The switch controller, power FETs, inductor, and all supporting components are included in the package. On-board input filters and noise cancellation circuitry enable low-noise operation, effectively reducing electromagnetic interference (EMI). The LTM4606 operates from an input voltage range of 4.5V to 28V and supports an output voltage range of 0.6V to 5V set by a single resistor. This high efficiency design provides 6A of continuous current (8A peak). Only high-capacity input and output capacitors are required to complete the entire design.

The use of high switching frequencies and adaptive on-time current mode architectures enables fast transient response to input voltage and load changes without sacrificing stability. The device supports output voltage tracking and output voltage margining.

In addition, you can make the micromodule (μModule^®) is synchronized with an external clock to reduce unwanted frequency harmonics and to implement polyphase^®) operation to provide high load current.

The LTM4606 is available in a space-saving, thermally enhanced 15mm × 15mm × 2.8mm LGA package, allowing unused space on the bottom of the pc board to be utilized for high density point-of-load regulation. The LTM4606 is Pb-free and RoHS compliant.
