ZHCSSA9 june 2023 TPS62901-Q1
PRODUCTION DATA
With MODE/S-CONF (SmartConfig), this device features an input with two functions. This pin can be used to customize the device behavior in two ways:
The TPS62901-Q1 interprets this pin during the start-up sequence after the internal OTP readout and before the device starts switching in soft start (see Figure 8-1). If the device reads a HIGH-level or LOW-level, the dynamic mode change is active and auto PFM/PWM or FPWM mode can be changed during operation. If the TPS62901-Q1 reads a resistor value, the device is configured according to the resistance value in Table 8-1 and there is no further interpretation during operation and device mode or other configurations can only be changed by power cycling or disabling the device.
