Functional Description
AAT1112 high performance 1.5A monolithic step-down converter operating 1.4MHz switching frequency. minimizes external component size optimizes efficiency over complete load range. Apart from small bypass input capacitor, only small filter required output. Typically, 3.3H inductor ceramic capacitor recommended 3.3V output (see table recommended values). dropout, converter duty cycle increases 100% output voltage tracks input voltage minus RDS(ON) drop P-channel high-side MOSFET (plus drop external inductor). device integrates extremely RDS(ON) MOSFETs achieve dropout voltage during 100% duty cycle operation. This advantageous applications requiring high output voltages (typically 2.5V) input voltages. integrated low-loss MOSFET switches provide greater than efficiency full load. operation
maintains high efficiency under light load conditions (typically <150mA). MODE/ SYNC allows optional "PWM only" mode. This maintains constant frequency output ripple across load conditions. Alternatively, synchronized external clock MODE/ SYNC input. External synchronization maintained between 0.6MHz 3.0MHz. battery-powered applications, decreases, converter dynamically adjusts operating frequency prior dropout maintain required duty cycle provide accurate output regulation. Output regulation maintained until dropout voltage, minimum input voltage, reached. 1.5A output load, dropout voltage headroom approximately 200mV. AAT1112 typically achieves better than ±0.5% output regulation across input voltage output load range. current limit 2.0A (typical) protects system components from short-circuit damage. Typical load quiescent current 42A.
