2.50 V (typ) voltage output: provides load current up to 3 mA,
for use as error amplifier reference input and for dead time
setting.
Oscillator timing capacity connection: should be used in the
capacity range 150 to 15000 pF.
Oscillator timing resistor connection: should be used in the
resistance range 5.1 to 100 k . This pin can also provide
output at voltage level V
reference input.
Error amplifier 1 non-inverting input pin.
Error amplifier 1 inverting input pin.
Error amplifier 1 output pin: connect resistor and capacitor
between this pin and the –IN1 pin to set gain and adjust
frequency characteristics.
OUT1 dead time setting pin: V
external resistor and applied to set dead time. Also, a capacitor
may be connected between this pin and the GND pin to
perform soft start operations.
