The SE3609 is a compact, high-fficiency,
synchronous step-up converter with power MOSFETs
integrated for a single-cell Lion/polymer battery. This
converter consumes only 100uA quiescent current
when no switching. When current load is light, this
converter enters burst mode to obtain high efficiency.
When current load is heavy enough, it enters
fixed-frequency PWM mode. It adopts peak current
mode for fast transient response with intemal
compensation. This converter contains cycle-by-cycle
current limiting and short protection circuit. It is
suitable for iPad-like computers, smart phones and
portable handheld devices. The device is packed in
PSOP8 package.
