Description
27
OUT_H2 CH-2 High side drive output CH-2 High side NMOS transistor drive for synchronous rectifier.
28
OUT_L2
CH-2 Low side driver output
CH-2 Low side NMOS transistor drive for synchronous rectifier.
Available even without Low side NMOS transistor.
30 SYSUVLO System UVLO input
SYSUVLO pin shuts down the IC, when the power supply voltage (Vin) is
lower than the predetermined voltage. The threshold voltage is 3.5V, the
release voltage is 5.46V. by internal setting. The threshold voltage also can
be set optionally by changing the external resistance value.
33
INV_HLDO
HVLDO amplifier inverting
input
HVLDO inverting input. The voltage on this pin is 1.2V in the normal oper-
ation.
34
OUT_HLD
O
