APPLICATION INFORMATION
OUTPUT VOLTAGE SETTING
Converter1 Adjustable Default Output Voltage Setting: TPS62400
The output voltage can be calculated to:
(4)
To keep the operating current to a minimum, it is recommended to select R12 within a range of 180k
to 360k.
The sum of R12 and R11 should not exceed ~1M. For higher output voltages than 3.3V, it is recommended to
choose lower values than 180k
for R12. Route the DEF_1 line away from noise sources, such as the inductor
or the SW1 line. The FB1 line needs to be directly connected to the output capacitor. A feedforward capacitor is
not necessary.
Converter1 Fixed Default Output Voltage Setting (TPS62401, TPS62402, TPS62403, TPS62404).
The output voltage VOUT1 is selected with DEF_1 pin.
Pin DEF_1 = low:
TPS62401, TPS62403, TPS62404 = 1.575V
TPS62402 = 1.2V
Pin DEF_1 = high:
TPS62401, TPS62403 = 1.1V
TPS62402: = 1.8V
TPS62404: = 1.9V
Converter 2 Adjustable Default Output Voltage Setting TPS62400:
The output voltage of converter 2 can be set by an external resistor network. For converter 2 the same
recommendations apply as for converter1. In addition to that, a 33pF feedforward Capacitor Cff2 for good load
transient response should be used. The output voltage can be calculated to:
(5)
Converter 2 Fixed Default Output Voltage Setting
ADJ2 pin must be directly connected with VOUT2
TPS62401, VOUT2 default = 1.8V
TPS62403, VOUT2 default = 2.8V
TPS62402, VOUT2 default = 3.3V
TPS62404, VOUT2 default = 3.3V
