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 AP3127/H current-mode PWM controllers. These devices are optimized for quick-charge applications in consumer portable products such as intelligent cell phone chargers and notebook adaptors and deliver a high-performance and cost-effective charging solution. Additional applications in the consumer electronics and communications markets include: set-top boxes, game consoles, modems and networking equipment.
In normal operation, the PWM switching frequency of the AP3127 and AP3127H controllers is internally fixed at 65kHz and 100kHz, respectively. However under moderate load conditions the device will enter a green mode that uses frequency fold-back to reduce the switching frequency for improved system efficiency, although a minimum switching frequency of 20kHz ensures any audible noise is avoided. Under no-load or light-load conditions, the ICs use a burst mode to minimize standby power while a built-in frequency dithering function reduces EMI emissions.
In addition to offering superior power control with higher average efficiency than pin-equivalent competitive products, the AP3127/H controllers include a comprehensive range of protection features to ensure stable, robust and reliable operation. These cover various overload and fault conditions such as over-current, secondary-side over-voltage (SOVP), internal over-temperature (OTP), and secondary-side under-voltage protection (SUVP), which protects a supply if its output cable is shorted.
