Intersil ZL9101M
The ZL9101M is a 12A variable output step-down PMBus-compliant digital power supply. The ZL9101M operates over a wide input voltage range and supports an output voltage range of 0.6V to 4V, which can be set by external resistors or via PMBus. This high efficiency power module is capable of delivering 12A.FEATURES

The I2C/SMBus requires pull-up resistors. Please refer to the I2C/SMBus specifications for more details. 2. The DDC bus requires a pull-up resistor. The resistance will vary based on the capacitive loading of the bus (and on the number of devices connected).
