REV.: 1/2019 RPX-3
DC/DC Converter
RPX-2.5
Series
Specifications (measured @ ta= 25°C, 12Vin, 3.3Vout, full load and after warm-up unless otherwise stated, refer to test set up)
UNDER VOLTAGE LOCKOUT SETTING
The RPX-2.5 features an internal UVLO circuit that disables the converter until the input voltage exceeds 4.1V typ. This threshold can be raised by adding
an external resistor divider R
UVLO1
and R
UVLO2
.
