AAT1343 Datasheet PDF

Advanced Analog Technology AAT1343

The AAT1343 provides an integrated two-channel pulse-width-modulation (PWM) solution for the z Precision Reference¡G 2.5V ± 1% (25 oC) power supply of DC-DC system; this device offers z Under-Voltage Lockout (UVLO) Protection the systems engineer flexibility to tailor-make the z Open Drain Output power supply circuitry for specific applications. The under-voltage protection, oscillator, short circuit protection and voltage z Wide Operating Frequency¡G reference circuit are the common features for these 10kHz to 800kHz two channels. 12 5 OE1 OE2 With a minimal number of external components, the 11 6 DTC1 DTC2 AAT1343 offers a simple and cost effective 10 OUT2 7 OUT1 solution.
