Description

The AAT1341 provides an integrated two-channel  pulse-width-modulation (PWM) solution for the  power supply of DC-DC system; this device offers  system engineers the flexibility to tailor-make the  power supply circuitry for specific applications.  Each channel contains its own error amplifier,  PWM comparator, dead¨Ctime control (DTC), and output driver. The under-voltage protection,  oscillator, short circuit protection and voltage  reference circuit are the common features of the two  channels.

Both channels of AAT1341 can be used for DC-DC  converter operations including step-up, step-down, and inverting. Dead-time control can be set to provide 0% to 100% dead-time through a resistive  divider network. Soft-start can be implemented by  paralleling the DTC resistor with a capacitor. Two  dead-time control inputs are assigned for CH1 and CH2 individually, and dead-time control inputs can  be used to control on / off operation. 

With a minimal number of external components, the  AAT1341 offers a simple and cost effective  solution.
