what this VOUT and IOUT stands for in TOP227 datasheet?

Posted by: yenlo on 10/08/2013

I am using TOP227 device, TOP221-227 TOPSwitch-II Family Three-terminal Off-line PWM Switch,

This datasheet is located : ( datasheet file is also attached here)

http://www.powerint.com/sites/default/files/product-docs/top221-227.pdf

In Figure 6 of Page 5 of this datasheet. There are 6 waveforms shown in following order:

VIN
DRAIN

VOUT
IOUT
VC
IC

Can anybody let me know what VOUY and IOUT stand for? Does it represent the Drain pin of TOP227 device? or it represents Output voltage and current of the whole converter? or.....?

Thanks.

Vout is the output voltage and Iout is the output current..

Thanks for some reply . Can you be more specific about where this Vout and Iout is located in a related schematic of this datasheet?

Without a clearly marked schematic, it will be hard to know what this Vout and Iout stands for exactly ?

Vout is the voltage across the output capacitors. And Iout is the output current of the power supply.

Regards

please be more specific about which node in a schematic of this datasheet, where is the Vout and Iout? this is an unclear technical reply from Power Integrator and can not be followed and understood for a customer.

Refer to FIG1 in the datasheet, Vout is the voltage across the output capacitor which is the capacitor after the output diode in the secondary side. And I out is the output current outside this capacitor..

Hopes can help ....
