This application note discusses the voltage regulators/switchers that are suitable for those processors running at 600 MHz. The TigerSHARC® processor requires three different supply voltages, the core voltage of 1.2 V, the internal DRAM voltage at 1.6 V, and the I/O voltage of 2.5 V. These three voltages are discussed in details in the following sections.

This datasheet provides detailed information on the MIC2169 500kHz PWM synchronous buck control IC. The IC is high-efficiency, easy to use, small package, and can operate from a 3V to 14.5V input voltage without the need for any additional bias voltage. The output voltage can be precisely regulated down to 0.8V. The adaptive all N-Channel MOSFET drive scheme allows efficiencies over 95% across a wide load range. The IC senses current across the high-side N-Channel MOSFET, eliminating the need for an expensive and lossy current-sense resistor. Current limit accuracy is maintained by a positive temperature coefficient that tracks the increasing RDS(ON) of the external MOSFET. Further cost and space are saved by the internal in-rush-current limiting digital soft-start. The IC is available in a 10-pin MSOP package with a wide junction operating range of -40°C to +125°C. All support documentation can be found on Micrel's web site.

The MIC2168 is a high-efficiency, simple to use 1MHz PWM synchronous buck control IC housed in a small MSOP-10 package. The MIC2168 allows compact DC/DC solutions with a minimal external component count and cost. The MIC2168 operates from a 3V to 14.5V input, without the need of any additional bias voltage. The output voltage can be precisely regulated down to 0.8V. The adaptive all N-Channel MOSFET drive scheme allows efficiencies over 95% across a wide load range. The MIC2168 senses current across the high-side N-Chan- Nel MOSFET, eliminating the need for an expensive and lossy current-sense resistor. Current limit accuracy is main- tained by a positive temperature coefficient that tracks the increasing RDS(ON) of the external MOSFET. Further cost and space are saved by the internal in-rush-current limiting digital soft-start. The MIC2168 is available in a 10-pin MSOP package, with a wide junction operating range of –40°C to +125°C. All support documentation can be found on Micrel’s web site at www.micrel.com.

The MIC2142 is a micropower boost switching regulator suitable for one-cell Li Ion and 3 to 4-cell alkaline/NiCad/NiMH applications. It features low quiescent current, adjustable output voltage, and is well suited for portable, space-sensitive applications.

The MIC2141 is a micropower boost switching regulator that can operate from 3- or 4-cell nickel-metal-hydride batteries or a single Li-ion cell. This regulator employs a constant 330kHz, fixed 18% duty-cycle, gated-oscillator architecture. The MIC2141 can be used in applications where the output voltage must be dynamically adjusted. The device features a control signal input which is used to proportionally adjust the output voltage. The control signal input has a gain of 6, allowing a 0.8V to 3.6V control signal to vary a 4.8V to 22V output. The MIC2141 requires only three external components to operate and is available in a tiny 5-lead SOT-23 package for space and power-sensitive portable applications. The MIC2141 draws only 70µA of quiescent current and can operate with an efficiency exceeding 85%.
