APPLICATION INFORMATION
TYPICAL APPLICATION CIRCUIT
Output Voltage Setting
The output voltage of the DCDC converters can be set by an external resistor network and can be calculated to:
(4)
with an internal reference voltage Vref, 0.6 V (typical).
It is recommended to set the total resistance of R1 + R2 to less than 1M
. The resistor network connects to the
input of the feedback amplifier; therefore, need some small feedforward capacitor in parallel to R1. A typical
value of 47pF is sufficient.
