Digital DC-DC Controller with Drivers and Pin-Strap Current Sharing

Description

Features

Power Conversion

The ZL2008 is a digital DC-DC controller with

integrated MOSFET drivers. Current sharing allows

multiple devices to be connected in parallel to source

loads with very high current demands. Adaptive

performance optimization algorithms improve power

conversion efficiency. Zilker Labs Digital-DC™

technology enables a blend of power conversion

performance and power management features.

Efficient synchronous buck controller

Adaptive light load efficiency optimization

3 V to 14 V input range

0.54 V to 5.5 V output range (with margin)

POLA and DOSA voltage trim modes

±1% output voltage accuracy

Internal 3 A MOSFET drivers

Fast load transient response

Current sharing and phase interleaving

Snapshot™ parameter capture

RoHS compliant (6 x 6 mm) QFN package

The ZL2008 is designed to be a flexible building block

for DC power and can be easily adapted to designs

ranging from a single-phase power supply operating

from a 3.3 V input to a multi-phase supply operating

from a 12 V input. The ZL2008 eliminates the need for

complicated power supply managers as well as

numerous external discrete components.

Power Management

Digital soft start / stop

Precision delay and ramp-up

Power good / enable

Voltage tracking, sequencing and margining

Voltage, current and temperature monitoring

I²C/SMBus interface, PMBus compatible

Output voltage and current protection

Internal non-volatile memory (NVM)

Key operating features can be configured by pin-straps,

including compensation, current sharing and output

voltage. The ZL2008 uses the I²C/SMBus™ with

PMBus™ protocol for communication with a host

controller and the Digital-DC bus for communication

between Zilker Labs devices.
