AAT1341 Details are subject to change without notice 2-CHANNEL SWITCHING REGULATOR FEATURES z Complete PWM Power Control Circuitry GENERAL DESCRIPTION The AAT1341 provides an integrated two-channel pulse-width-modulation (PWM) solution for the z Under-Voltage Lockout (UVLO) Protection power supply of DC-DC system; this device offers z Open Drain Output system engineers the flexibility to tailor-make the z Output Short Circuit Protection power supply circuitry for specific applications. z Low Dissipation Current¡G 1.6mA Each channel contains its own error amplifier, z Dead-Time Control¡G 0 % to 100% PWM comparator, dead–time control (DTC), and z Wide Operating Frequency¡G output driver. The under-voltage protection, oscillator, short circuit protection and voltage 10kHz to 800kHz reference circuit are the common features of the two z VDD Range¡G 4.0V to 14.0V channels. DataSheet4U.com DataShee Both channels of AAT1341 can be used for DC-DC PIN CONFIGURATION converter operations including step-up, step-down, and inverting. Dead-time control can be set to TO PV IE W provide 0% to 100% dead-time through a resistive Ct 16 V 1 divider network. Soft-start can be implemented by R EF paralleling the DTC resistor with a capacitor. Two 15 Rt 2 SC P dead-time control inputs are assigned for CH1 and 14 3 N E2 N E1 CH2 individually, and dead-time control inputs can 13 IE2 IE1 4 be used to control on / off operation. 12 5 O E2 O E1 Wi...
