PRODUCTION DATA.
The TPS59632-Q1 device continuously monitors the voltage on the V5A, VDD, and VINTF pin to ensure a value high enough to bias the device properly and provide sufficient gate drive potential to maintain high efficiency. The converter starts with approximately 4.4 V and has a nominal 200 mV of hysteresis. Once the 5VA,VDD, or VINTF goes below the VUVLOL , the corresponding voltage must fall below VPOR (1.5 V) to reset the device.
The input (VBAT) does not include a UVLO function, so the circuit runs with power inputs as low as approximately 3 × VOUT.
