TYPICAL PERFORMANCE CHARACTERISTICS
RVTRANS (Pin 1/Pin 19): Transformer Supply Sense Pin.
Connect a resistor between the RVTRANS pin and the
VTRANS supply. Refer to Table 2 for proper sizing of the
RVTRANS resistor. The minimum operation voltage for
VTRANS is 4.75V.
UVLO1 (Pin 2/Pin 20): VTRANS Undervoltage Lockout Pin.
Senses when VTRANS drops below:
V
UVLO1 = 1.225 + 50μA RUVLO1
and trips the FAULT latch low, disabling switching. After
VTRANS rises above VUVLO1, toggling the CHARGE pin
reactivates switching.
OVLO1 (Pin 3/Pin 1): VTRANS Overvoltage Lockout Pin.
Senses when VTRANS rises above:
V
OVLO1 = 1.225 + 50μA ROVLO1
and trips the FAULT latch low, disabling switching. After
VTRANS drops below VOVLO1, toggling the CHARGE pin
reactivates switching.
UVLO2 (Pin 4/Pin 2): VCC Undervoltage Lockout Pin.
Senses when VCC drops below:
V
UVLO2 = 1.225 + 50μA RUVLO2
and trips the FAULT latch low, disabling switching. After
VCC rises above VUVLO2, toggling the CHARGE pin reac-
tivates switching.
OVLO2 (Pin 5/Pin 3): VCC OvervoltageLockoutPin.Senses
when VCC rises above:
V
OVLO2 = 1.225 + 50μA ROVLO2
and trips the FAULT latch low, disabling switching. After
VCC drops below VOVLO2, toggling the CHARGE pin reac-
tivates switching.
FAULT (Pin 6/Pin 4): Open Collector Indication Pin. When
either VTRANS or VCC exceeds the user-selected voltage
range, or an internal UVLO condition occurs, a transistor
turns on. The part will stop switching. This pin needs a
proper pull-up resistor or current source.
