G0 and G2 models can be downloaded from above linkage destination. The following shows the actual measurement of R-Load switching turn off waveform of the low voltage MOSFET device and L-load switching turn off waveform of the mid to high voltage MOSFET device, and the simulated waveforms of the G0 model and G2 model, respectively. While the SPICE models we have been publishing (called the G0 model in Toshiba) are standard device models and are suitable for function checking because of their fast computing speed, the SPICE models we have started publishing this time (also called the G2 model) enhance the reproducibility of the high current region characteristics of I D-V DS curve and the voltage-dependent characteristics of the parasitic capacitance, allowing us to simulate the switching with higher accuracy closer to actual measurement. In addition to those currently being published, Toshiba has begun publishing high precision SPICE models with high reproducibility of transient characteristics.
The on-board remote sense amplifier is not available in the LTM4601-1.ġ35 (for stronger solder joint stability) An on-board differential remote sense amplifier can be used to accurately regulate an output voltage independent of load current. The μModule regulator can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase ® operation for high load currents.Ī high switching frequency and adaptive on-time current mode architecture deliver a very fast transient response to line and load changes without sacrificing stability.

The low profile and light weight package easily mounts in unused space on the back side of PC boards for high density point of load regulation. Only bulk input and output capacitors are needed to complete the design. The high efficiency design delivers 12A continuous current (14A peak). Operating over an input voltage range of 4.5V to 20V, the LTM4601 supports an output voltage range of 0.6V to 5V as well as output voltage tracking and margining.
The μModule ® regulator is housed in small surface mount 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. The LTM4601 is a complete 12A step-down switch mode DC/DC power supply with on-board switching controller, MOSFETs, inductor and all support components.
