Buck Converter from Diodes Inc raises portable efficiency
Plano, TX - Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the AP3403. Achieving typical efficiencies greater than 95%, this miniature step-down DC-DC converter helps lengthen the battery lifetime of smartphones and other low-voltage portable products. The AP3403 is a synchronous PWM converter that drives a load at up to 600mA, maintaining high efficiency through a configuration of external resistor, capacitor and inductor components.
To support mini Li-Ion battery operation, the input voltage range is low at 2.7V to 5V, with no-load current being only 34µA. The buck converter ensures excellent line and load regulation and employs current mode control to deliver fastest possible transient response and cycle-by-cycle current limit.
By operating at a ripple-reducing fixed 2MHz, the AP3403 is able to help reduce the cost and size of external circuit components, while its ultra-small, thermally efficient U-DFN1616 package further aids a reduction in overall circuit footprint.
The converter’s output voltage range of 0.7V to 5.5V makes it easily configurable to application requirements. System integrity is maintained by a comprehensive array of built-in features that include under-voltage lockout, over-temperature protection, hiccup mode short-circuit protection, and soft-start functionality.
