The AP3428KTTR-G1 from Diodes Incorporated is a 1A step-down DC-DC buck converter designed for efficient power regulation. It supports a wide input voltage range from 2.5V to 5.5V, making it suitable for various power sources including single Li-polymer cells or multiple alkaline/NiMH cells.
The converter offers an adjustable output voltage, ranging from 0.6V up to the input voltage. It operates at a constant switching frequency of 1.5MHz, utilizing internal power switches and a synchronous rectifier to minimize external component count and achieve high efficiency. The device includes features such as over-temperature protection, short circuit protection, and under-voltage lockout to ensure system reliability and protect the battery from deep discharge.
With a low no-load quiescent current of 40µA (typical) and a shutdown current of less than 1µA, the AP3428KTTR-G1 is ideal for power-sensitive applications. It is available in a compact TSOT-25 package, suitable for surface mount assembly.
Key electrical characteristics include a 1A maximum output current, a 0.6V reference voltage with ±2% precision, and 100% duty cycle operation. The constant-frequency PWM control ensures excellent stability and transient response, with no external compensation components required. Pulse skip mode is employed to maintain high efficiency under light-load conditions.
