INTEGRATED
3-A POWER MANAGEMENT AND CONVERSION IC
The ZL2105 is
the industry’s only single-chip 3-A power conversion
solution that integrates full digital power management
capabilities. The IC combines a synchronous step-down
converter, including synchronous power MOSFETs, with
key power management functionality in a tiny 6 mm ×
6 mm package. A ZL2105 circuit with full digital power
management capabilities requires less than two square
centimeters of board space, representing size and component
count reductions of up to 50%. Like all Digital-DC ICs,
the ZL2105 is designed to be a digital building block
that can be seamlessly combined with other Digital-DC
devices to provide a comprehensive solution for board-mounted
power management and conversion.

The Digital-DC products are fully configurable with simple pin-strap connections,
resistor selection, or via the device’s on-board serial
port using the industry-standard PMBus command set.
The single-chip Digital-DC products provide the configurability,
control, and monitoring capabilities of digital power
technology without compromising efficiency. Additionally,
they eliminate the requirement for user programming.
To combine multiple Digital-DC ICs in a given application,
the designer simply configures each IC via pin-strap
selection and connects the SMBus of each device. The
devices then communicate with each other via the bus
and can operate independent of a host controller. The
devices can be monitored and controlled individually
or as a system.
The ZL2105 is available in a 36-lead QFN package. Pricing starts at $2.80
in quantities of 1,000. An evaluation kit, the ZL2105EV1,
is also available.
