Advanced Power Electronics Corp. (USA), a Taiwanese manufacturer of MOS power semiconductors for DC-DC power conversion applications, has updated two of its most popular PWM controllers to provide customers with space saving and more cost effective devices without sacrificing performance and reliability.
The APE3061 PWM controller is now available in a small 8-lead DFN package, reducing package size down from 5 x 6mm (SO-8) to 3 x 3mm, without any negative impacts on power handling capability. The new APE3061GN3-HF-3 component supports input voltages from 3V up to 24V and is designed to drive an external N-channel MOSFET.
The output voltage is dependent on the external N-MOSFET and is programmable using an internal reference voltage of 1.0V and external resistors connected as a voltage divider. The controller benefits from built-in enable and thermal shutdown functions. Switching frequency is fixed, around 500kHz, allowing for easy filtering and low noise.
