Terminal Functions
TERMINAL
I/O DESCRIPTION
NAME NO.
EN 1 I Enable. Pulling EN to ground forces the device into shutdown mode. Pulling EN to V
I
enables the device. EN
should not be left floating and must be terminated.
VIN 2, 3 I Supply voltage input
GND 4 Analog ground
FB 5 I Feedback. Connect an external resistor divider to this pin.
If a fixed-output-voltage device is ued, connect FB directly to the output.
MODE 6 I The difference between TPS6202x and TPS62021 is the logic level of the MODE pin. The TPS62021 has an
MODE active-low MODE pin. The TPS6202x is forced into fixed-frequency PWM mode by pulling the MODE pin high.
Pulling the MODE pin low enables the Power Save Mode, operating in PFM mode (Pulse frequency modulation)
at light load current, and in fixed frequency PWM at medimum to heavy load currents. In contrast, the TPS62021
is forced into PWM mode by pulling the MODE pin low.
SW 7, 8 I/O This is the switch pin of the converter and connected to the drain of the internal power MOSFETs
PGND 9, 10 Power ground
