8.2 Functional Block Diagram
8.3 Feature Description
8.3.1 Undervoltage Lockout
The undervoltage lockout circuit prevents the device from misoperation at low input voltages. It prevents the
converter from turning on the switch or rectifier MOSFET under undefined conditions. The TPS6223x devices
have a UVLO threshold set to 1.8 V (typical). Fully functional operation is permitted for input voltage down to the
falling UVLO threshold level. The converter starts operation again once the input voltage trips the rising UVLO
threshold level.
8.3.2 Enable and Shutdown
The device starts operation when EN is set high and starts up with the soft-start as previously described. For
proper operation, the EN pin must be terminated and must not be left floating, except for the TPS622319, which
has an integrated 1MΩ always active pull-down resistor.
Pulling the EN pin low forces the device into shutdown, with a shutdown quiescent current of typically 0.1 μA. In
this mode, the P- and N-channel MOSFETs are turned off, the internal resistor feedback divider is disconnected,
and the entire internal-control circuitry is switched off.
The EN input can be used to control power sequencing in a system with various DC – DC converters. The EN
pin can be connected to the output of another converter, to drive the EN pin high and getting a sequencing of
supply rails.
8.3.3 Thermal Shutdown
As soon as the junction temperature, TJ, exceeds 150°C (typical) the device goes into thermal shutdown. In this
mode, the high-side and low-side MOSFETs are turned off. The device continues its operation when the junction
temperature falls below the thermal shutdown hysteresis.
