Monolithic CMOS power amp cuts GSM consumption
The Si4300 is billed as the industry's first monolithic CMOS power amplifier (PA) for GSM cellular applications.
MCU incorporates high-resolution conversion
The C8051F350 is precision mixed-signal microcontroller that integrates an eight-channel, 24bit ADC with a high-speed 8051-compatible CPU.
The tool dramatically shortens the digital power learning curve, enabling analogue engineers to rapidly implement digitally controlled power systems.
The Si8250DK supports Silicon Laboratories' Si825x family of digital power supply controllers, which offer the fast response of an ASIC solution and the flexibility of a Flash-based processor.
The unique Si825x architecture delivers both digital power control and management functions while consuming one-tenth the space and drawing less than 15% of the supply current of typical digital signal processor (DSP) solutions.

"The industry-leading integration, performance and flexibility of the Si825x make it ideal for high-performance power supplies in communications systems, computers, servers and industrial and medical equipment", said Don Alfano, Director of Power Products for Silicon Laboratories.
"The Si8250DK development kit was created to enable analogue power designers using the Si825x digital controllers to quickly become proficient in digital power supply design".
The Si8250DK includes a source-level, real-time kernel that supplies key system software functions including power supply initialisation, soft-start, fault detection and recovery, PMBus management and shutdown.
The kit includes powerful GUI-based Application Builder software that enables the user to design and verify system switch timing, loop compensation and configuration without writing application software.
Also included is an integrated development environment (IDE) consisting of an editor, macro assembler, demo C compiler and a special online debugger that allows the user to manually adjust system parameters (such as loop compensation) during power supply operation.
The Si8250DK development kit includes everything needed to develop applications with the Si825x: a Si8250 target board featuring an isolated half-bridge current doubler rectifier; a USB to SMBus bridge board; a USB debug adapter and USB cable; two 9V, 1.5A universal power supplies; and Silicon Laboratories' IDE and product information CD-ROM that includes the Keil 8051 development tools (macro assembler, linker, evaluation C compiler), source code examples and register definition files, the Si825x kernel, waveform builder and compensator design tools, PMBus monitor software and documentation.
The Si8250DK is available now for $199 and can be purchased online.
