AP3429AKTTR-G1 – Buck Switching Regulator IC 2A SOT-23-5
The AP3429AKTTR-G1 from Diodes Incorporated is a high-efficiency 2A synchronous step-down (buck) DC-DC converter designed for compact, low-power, and battery-operated systems. Operating over a wide input voltage range of 2.7V to 5.5V, it efficiently converts single-cell Li-Ion/Li-Polymer or multiple alkaline/NiMH cell power sources into regulated outputs ranging from 0.6V up to VIN. This device integrates both the power switch and synchronous rectifier, reducing external component count and achieving excellent efficiency and thermal performance. It uses constant-frequency PWM control at heavy loads, ensuring fast transient response and stable operation without the need for external compensation components. At lighter loads, the AP3429A maintains high efficiency with a typical quiescent current of just 90uA, while in shutdown mode, the current drops below 1uA to conserve battery life.
The AP3429AKTTR-G1 also includes comprehensive protection features such as over-temperature protection (OTP), short-circuit protection (SCP), and under-voltage lockout (UVLO) to prevent deep battery discharge and enhance overall system reliability. Its 100% duty cycle operation ensures low dropout performance, making it ideal for high-current, low-voltage power rails in portable devices and embedded applications.
