The AAT1218IWP-1.2-T1 from Skyworks Solutions is a general-purpose DC/DC synchronous boost converter capable of providing a tightly regulated DC output voltage for continuous output currents up to 1A. It operates with an input voltage range of 0.5V to 5.5V, making it suitable for portable equipment and consumer appliances.
This device features an adjustable output voltage programmed from 2.5V to 5.5V via an external resistor divider. It boasts high efficiency up to 95% and a switching frequency internally set to 1.2MHz to minimize external filter size. Synchronous rectification is integrated, eliminating the need for an external Schottky diode for output voltages less than 4.5V. The converter includes integrated soft-start circuitry to limit inrush current and an anti-ring circuit to reduce EMI.
The AAT1218IWP-1.2-T1 is available in a Pb-free, 12-pin low profile TDFN33 package, designed for surface mount applications. It operates within a junction temperature range of -40°C to 150°C and includes cycle-by-cycle current limit and over-temperature protection.
Key electrical specifications include an output accuracy of ±2%, standby current less than 400μA, and shutdown current less than 1μA. The low output ripple is less than 80mVpp across all loading conditions.
