High Current Step Down DC/DC Converter

タイトルまたは説明

BCT***3S Vin (4.5V ~ *0V) & Vout (0.8V ~ *6V) up to 3A The BCT***3S is a step down monolithic regulator with a built-in internal power MOSFET, capable of driving up to 3A continuous output current with excellent line and load regulation. The output voltage can be set from 0.8V to *6V. Requiring a minimum number of external components, it offers simple to use, but high efficiency and advanced protection features including pulse-by-pulse current limiting and thermal shutdown. Adjustable soft-start reduces the stress on the source at turn-on and the regulator draws only *0uA in shutdown mode. BCT***3S is available in a Pb-Free SOIC8 with Exposed Pad package FEATURES • Wide Vin Range: 4.5 to *0V • Typical 0.5% Reference Accuracy • 3A Output Current • High Efficiency up to *5% • Output Adjustable from 0.8 to *6V • **0KHz Fixed Frequency internal oscillator • *0uA Shutdown Mode • Pulse-to-Pulse Over Current Protection • Thermal Shutdown • Automatic Start-Up when EN floating • Controllable Soft Start • Compact SOIC8 with Exposed Pad APPLICATIONS • Simple High Efficiency Step-down • Flat Panel LCD/PDP TV, Monitor • Consumer: STB, DVD, VCR • Car Audio/PMP/Navigation • Battery Charger • Pre-Regulator for Linear Regulators
