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.
