AT1314

1. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitordischarged through a 1.5K resistor into each pin.

AT1314 is a voltage-mode PWM step-down DC-DC converter capable of driving up to 1A loads over a wide input supply range with excellent line and load regulation characteristics. High efficiency is obtained through the use of a low Rds(on) P-channel power switch.

AT1314 uses a fixed switching frequency up to 600KHz thus allowing smaller sized components. The output voltage level is user-programmable via an external resistive voltage divider. The built-in soft-start can reduce inrush current on the input source at turn on.

AT1314 also has built-in cycle-by-cycle current-limit, thermal shutdown, under-voltage lockout and an ON/OFF logic-control that can power down the regulator to a shutdown mode. In shutdown mode the regulator draws less than 20uA of supply current.

AT1314 is available in SOP-8 package.
