General Description
The G5321 is a wide input voltage (4.5V to 27V),
non-synchronous boost controller. It is suitable for
topologies including boost, flyback, SEPIC and
various LED Driver applications which require a
grounded source N-channel FET. The device fea-
tures include programmable soft start, over current
protection with automatic retry, programmable os-
cillator frequency and integrated Low-side driver.
Current mode control provides improved transient
response and simplified loop compensation.
