سلام
یه مدار معادل و دقیقا با مشخصات مدار زیرمیخوام که قطعاطش قابل تهیه باشه از اقایون واساتید کسی میتونه کمکم کنه ممنون میشم راهنمایی کنید تصاویر پیوست شده http://www.irantk.ir/attachment.php?attachmentid=125075&stc=1&d=1444155146
( Internal Step-Up Switching Regulator
Cell-Input Operation Fixed 9-V Output
3V to 9V dc converter
How it works.
– When connecting the battery to the input pin 2, which may be a one battery pack (voltage 1.1 -1.5 volt) or 2 pieces (pressure 2.3 – 3 volt). At low voltage circuit starts. This low voltage circuit starts, the feedback voltage to bias to transistors inside the integrated circuit. This means that a short circuit, L1 is connected to pin 6 to ground, resulting in the accumulation of energy in the form of a magnetic field on current in L1 increases until a maximum value at about 1 amp.
– The IC internal circuit will reset itself. As a result, the transistor stops (open circuit), so there is no current flow, the magnetic field in the coil L1 will collapsing. The induced current flows into At pin 6, lead to increased pressure within the IC be 9 volt out to pin 8(output pin
