DC-DC converter features pin-strap compensation

Intersil

ZL2008 step-down DC-DC converter

Intersil has introduced the ZL2008, a synchronous step-down DC-DC converter with pin-strap compensation and current sharing.

Taking advantage of Zilker's Digital-DC technology, the ZL2008 is designed for digital power supply module and system designers that demand easy-to-use board-level power supply configuration.

The compensation and transient response of the ZL2008 can be optimised for load current and output capacitance by adjusting resistor pin-straps.

Current sharing of up to eight devices in parallel with individual phase enable/disable pins is configurable.

Power management features such as digital soft-start delay and ramp, sequencing, tracking and margining are easy to implement.

Power supply reliability and availability can be improved through real-time monitoring using the I2C/SMBus interface with the PMBus protocol.

The ZL2008 includes the Digital-DC bus for interoperability between Zilker Labs devices to simplify power and fault management.

Customers can use the entire range of Digital-DC devices for all DC power conversion and management needs.

The ZL2008 is a synchronous buck converter with integrated 3A Mosfet drivers that operate on single supply from 3V to 14V.

Output voltages range from 0.54V to 5.5V with +/-1 per cent output voltage accuracy and 200kHz to 1.4MHz operation.

In addition, there is current sharing with individual phase enable/disable pins, optional IC/SMBus configuration, and external clock synchronisation.

Power management features include coincidental/ratiometric tracking, power up/down sequencing, voltage margining, plus voltage and current monitoring, as well as internal temperature monitoring.

There is extensive fault handling for all parameters thanks to the on-board Snapshot parameter capture.

The product also has on-chip non-volatile memory (NVM) for storing custom configurations.

The ZL2008 is available in 6mm x 6mm 36-lead QFN package.
