Austin, Tex.Zilker Labs Inc. has introduced a DC-DC power controller that meets voltage regulation accuracy requirements of high-performance embedded processors and ASICs.
The ZL2004-01 uses Zilker Labs' Digital-DC technology to provide ±0.2% DC output regulation, delivering accurate power to sensitive devices. 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 eight devices in parallel to supply load current requirements in excess of 100A.
Zilker also introduced the ZL1505 high-speed, high-current synchronous N-channel MOSFET driver, which provides high power conversion efficiency at loads up to 40A per phase. Specifically designed for use with the ZL2004 Digital-DC controllers, the ZL1505 uses 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.
Pricing: In 1,000-unit quantities, the ZL2004-01 is available in a 5 x 5 mm 32-lead QFN package for $3.60 and the ZL1505 is available in a 3 x 3 mm DFN package starting at $0.71.
Availability: Production quantities.
Datasheets: ZL2004 and ZL1505.
