开关稳压器 Micropower DC/DC Converter Flash Memory VPP Generator Adjustable and Fixed 5V, 12V
The is a simple step-up DC/DC Converter that requires only four external components. Current drain is just 360µA at no load, making the device ideal for cost-sensitive applications where standby current must be kept to a minimum. The LT1109A-12 can deliver 12V at over 150mA from a 5V supply, enough power to program four flash memory chips simultaneously. The converter features a shutdown pin that turns off the oscillator when taken low. The gated oscillator design requires no frequency compensation components. High frequency 120kHz operation permits the use of small surface mount inductors and capacitors.
