<description><h1>DC-DC Converter</h1>
<h2>5-A, 28-V Input, Step-Down SWIFT&trade; DC-DC Converter with Eco-Mode&trade;</h2>
<h3>Documentation</h3>
<ul>
<li><a href="http://www.ti.com/lit/ds/symlink/tps54531.pdf">Datasheet</a></li>
</ul>
<h3>Description</h3>
The TPS54531 device is a 28-V, 5-A non-synchronous buck converter that integrates a low R<sub>DS(on)</sub> high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode feature is automatically activated. Furthermore, the 1-uA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots during startup and transient conditions. A cycle-by-cycle current-limit scheme, frequency fold back, and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54531 device is available in 8-pin SO PowerPAD&trade; package that has been internally optimized to improve thermal performance.
<h3>Features</h3>
<ul>
<li>3.5 to 28-V Input Voltage Range</li>
<li>Adjustable Output Voltage Down to 0.8V</li>
<li>Integrated 80-m&Omega; High-Side MOSFET Support</li>
<li>High Efficiency at Light Loads with a Pulse Skipping Eco-mode&trade;</li>
<li>Fixed 570kHz Switching Frequency</li>
<li>Typical 1uA Shutdown Quiescent Current</li>
<li>Adjustable Slow Start Limits Inrush Currents</li>
<li>Programmable UVLO Threshold</li>
<li>Overvoltage Transient Protection</li>
<li>Cycle-by-Cycle Current-Limit, Frequency Fold Back, and Thermal Shutdown Protection</li>
<li>Availabel in Easy-to-Use Thermally Enhanced 8-Pin SO PowerPAD&trade; Package</li>
</ul>
<h3>Applications</h3>
<ul>
<li>Consumer Applications such as Set-Top Boxes, CPE Equipment, LCB Displays, Peripherals, and Battery Chargers</li>
<li> Industrial and Car Audio Power Supplies</li>
<li>5-V, 12-V and 24-V Distributed Power Systems</li>

Furthermore, the 1-uA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots during startup and transient conditions. A cycle-by-cycle current-limit scheme, frequency fold back, and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54531 device is available in 8-pin SO PowerPAD&trade; package that has been internally optimized to improve thermal performance.

<h3>Documentation</h3>

</ul>
<h3>Description</h3>
The TPS54331 device is a 28-V, 3-A non-synchronous buck converter that integrates a low R<sub>DS(on)</sub> high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode feature is automatically activated. Furthermore, the 1-uA shutdown supply current allows the device to be used in battery powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots during startup and transient conditions. A cycle-by-cycle current-limit scheme, frequency fold back, and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54331 device is available in 8-pin SOIC package and 8-pin SO PowerPAD package that has been internally optimized to improve thermal performance.

<h3>Description</h3>
<p>
The OPA171, OPA2171 and OPA4171 (OPAx171) are a family of 36V, single-supply, low-noise operational amplifiers with the ability to operate on supplies ranging from +2.7V (±1.35V) to +36V (±18V). These devices are available in micro-packages and offer low offset, drift, and bandwidth with low quiescent current. The single, dual, and quad versions all have identical specifications for maximum design flexibility.
</p>
<p>
Unlike most op amps, which are specified at only one supply voltage, the OPAx171 family is specified from +2.7V to +36V. Input signals beyond the supply rails do not cause phase reversal. The OPAx171 family is stable with capacitive loads up to 300pF. The input can operate 100mV below the negative rail and within 2V of the top rail during normal operation. Note that these devices can operate with full rail-to-rail input 100mV beyond the top rail, but with reduced performance within 2V of the top rail.
</p>
<p>
The OPAx171 series of op amps are specified from -40<sup>o</sup>C to +125<sup>o</sup>C.
