The MCP1640-I/MC is a 0.65V start-up synchronous Boost Regulator with true output disconnect or input/output bypass option. The MCP1640 is a compact high-efficiency fixed frequency synchronous step-up DC-DC converter provides an easy-to-use power supply solution for applications powered by either one-cell, two-cell or three-cell alkaline, NiCd, NiMH, one-cell Li-ion or Li-polymer batteries. It provides very high efficiency through integration of the low resistance N-channel boost switch and synchronous P-channel switch. Low-voltage technology allows the regulator to start-up without high inrush current or output voltage overshoot from a low 0.65V input. High efficiency is accomplished by integrating the low resistance N-channel boost switch and synchronous P-channel switch. All compensation and protection circuitry is integrated to minimize the number of external components.
- Up to 96% typical efficiency
- 800mA Typical peak input current limit
- 0.65V Low start-up voltage
- 0.35V Operating input voltage
- Automatic PFM/PWM operation
- PWM operation at 500kHz
- 19µA Typical PFM mode low device quiescent current
- <1µA Shutdown current (all states)
- Internal synchronous rectifier
- Internal compensation
- Inrush current limiting and internal soft-start
- True load disconnect shutdown
- Low noise, anti-ringing control
- Over-temperature protection

A wonderful telling of history.
Format: Kindle
A wonderful telling of history by an enjoyable author. It isn't light reading per se but if you want a read that will enhance your understanding of the American people this is a good book.

Scholarly and Readable, Too
Format: Paperback
I read the first volume in this series (about the Great Depression), and now I'm in the midst of this one. Kennedy's very-lucid prose keeps the reader moving along, and of course, the sweep of the story he's telling is nearly-irresistible. But in lamer hands, the prose might well have bogged down in turgidity--not so in this case!

Good but not as good
Format: Kindle
Freedom From Fear #1 was one of the most interesting and informational books I've ever read. Part Two was interesting but I did not learn much more about the war than I had known before other than the fact that, while Japan lost the war, Anglo-Saxons are no longer in control in the Far East. I somewhat disagree with his ending ideas about the "good" war, that it wasn't so "good" after all in it's outcome. However, those who fought in it and their families would probably disagree.
