Zilker Labs, Inc., introduced the industry’s most accurate DC-DC power controller for meeting the ever-increasing voltage regulation accuracy requirements of today’s high-performance embedded processors and ASICs. The ZL2004-01 uses Zilker Labs’ innovative Digital-DC technology to provide ±0.2% DC output regulation, enabling the most integrated and cost-effective solution for delivering accurate power to sensitive devices.
“The smaller process geometries of today’s high-performance processors and ASICs have placed a tremendous burden to regulate the core voltage within limits not possible using traditional implementations,” said Jim MacDonald, Vice President of Marketing and Applications at Zilker Labs. “The ZL2004-01 delivers ±0.2% DC output regulation in the industry’s smallest footprint to address this increasingly critical need.”
The ZL2004-01 interfaces with external drivers and MOSFETs, providing a flexible controller that can be implemented using a wide variety of power train components. The device also supports active current sharing, allowing up to 8 devices in parallel to supply load current requirements in excess of 100A. The ZL2004-01 can be seamlessly combined with other Digital-DC ICs to provide a comprehensive and intelligent system power solution. Zilker Labs’ Digital-DC products are fully configurable with simple pin-strap connections, resistor selection or via the on-chip I2C/SMBus compliant serial port using the industry-standard PMBus[tm] (Power Management Bus) command set. The devices can be configured and monitored individually or as a system through the I2C/SMBus interface. All of Zilker Labs’ Digital-DC products support monitoring of voltage, current, temperature and other system parameters without additional components.
Also available today is the new ZL1505 high-speed, high-current synchronous N-channel MOSFET driver, which provides the industry’s highest power conversion efficiency at loads up to 40A per phase. Specifically designed for use with the ZL2004 Digital-DC controllers, the ZL1505 utilizes dual PWM inputs to enable the controller to provide dynamic dead-time optimization that maximizes power conversion efficiency in response to changing system operating conditions with no user interaction or additional components needed. The device combines a 3A high-side drive with a 4A low-side drive to enable high efficiency at high step-down ratios and high switching frequency. The ZL1505 operates from a 4.5V to 7.5V gate drive supply and can be used in step-down applications with an input supply of 3V to 24V. The ZL1505 also provides an adjustable gate drive current feature that uses simple pin-strap connections to configure the low-side gate driver and the high-side driver for 50% or 100% of its rated drive current, enabling performance optimization across a wide range of input/output voltage and output current requirements.
