This is a power module that supports input voltage of 2.7V to 5.5V, output voltage of 1.8V and 1.2V, and maximum continuous output current of 8A.
This document is a demonstration manual for the DC1245A circuit board, which features the LTM4616 dual 2.7VIN to 8A step-down µModule regulator. The manual describes the module's capabilities, including high efficiency, high density, and the ability to synchronize switching frequencies or parallel channels for higher output currents.
| Input Voltage Range | 2.7V to 5.5V |
|---|---|
| Maximum Continuous Output Current | 8A Each Channel |
| Default Operating Frequency | 1.5MHz |
| Efficiency | 77.5% |
The rated load current is 8A for each channel, though derating is necessary for certain VIN, VOUT, and thermal conditions.
Yes, by applying a clock signal to the CLKIN pin, the module's switching frequency may be synchronized from 0.75MHz to 2.25MHz.
Channel 2 is set up to synchronize to the CLKOUT signal of channel 1 with a default phase difference of 180°.
