The SD8421 devices are high-performance,fixed
frequency,current-mode PWM step-up DC/DC
conver ter that incorporate internal power MOSFET
that supports peak currents of up to 3A/4.5A/5.5A
The SD8421 utilizes simple external loop
compensation allowing optimization between
component size,cost,and AC performance across
a wide range of applications.Additional functions
include an externally programmable
soft-start function for easy inrush
current control,internal over-voltage
protection (OVP),cycle-by-cyc le
current limit protection,under voltage
lock-out and thermal shutdown.
The SD8421 is available in the small SOP-8(EP)
