DC/DC Converters Enhance Consumer Designs

The AP6502 and AP6503 synchronous dc/dc buck converters are tailored for use in consumer electronics systems such as digital TV, LCD monitors and set-top boxes. Capable of handling continuous load currents of up to 2A or 3A, respectively, the AP6502 and AP6503 can support 12V and 5V bus systems and achieve efficiency rates as high as 95%. Output voltage is set via an external resistor divider that can accommodate any output voltage setting down to 0.925V. Switching frequency is 340 kHz. Available in an SO-8EP package, prices for the AP6502 and AP6503 are $0.25 and $0.32 each/10,000, respectively. DIODES INC., Dallas, TX. (972) 385-2810.
