BOFO (Boost Follower setting)
An external DC voltage to this pin indicating the PWM
output power which can be set to enter the Boost
follower low step.
ISENSE (Current Sense Input)
The ISENSE Pin senses the voltage drop at the
external sense resistor (R
for the average current regulation in the current loop. It
is also fed to the peak current limitation block.
During power up time, high inrush currents cause high
negative voltage drop at R
pin 2 which could be beyond the absolute maximum
ratings. Therefore a series resistor (R
is recommended in order to limit this current into the IC.
SGND (Signal Ground)
The ground potential of the IC.
ICOMP (Current Loop Compensation)
Low pass filter and compensation of the current control
loop. The capacitor which is connected at this pin
integrates the output current of OTA6 and averages the
current sense signal.
FREQ (Frequency Setting)
This pin allows the setting of the operating switching
frequency by connecting a resistor to ground. The
frequency range is from 21kHz to 250kHz.
VB_OK (Bulk Voltage OK signal)
This pin is pulled up to 5V internally once the bulk
voltage is higher than 95% rated voltage and pulled
down to ground once VSENSE pin is lower than preset
VBTHL_EN threshold. This signal can enable the PWM
IC or control the inrush relay.
VBTHL_EN
An external voltage reference can be applied to
VBTHL_EN to set the turn-off threshold of VB_OK
signal. The IC can be shut down by pulling the pin lower
than 0.5V
VREF (Voltage Reference)
This pin is the 5V regulator output with a 5mA sourcing
current (minimum).
