SLVS872B – JUNE 2009 – REVISED DECEMBER 2009
If the output voltage drops below the input voltage the backgate diode of the rectifying switch gets forward biased
and current starts flow through it. Because this diode cannot be turned off, the load current is only limited by the
remaining DC resistances. As soon as the overload condition is removed, the converter automatically resumes
normal operation and enters the appropriate soft start mode depending on the operating conditions.
Undervoltage Lockout
An undervoltage lockout function stops the operation of the converter if the input voltage drops below the typical
undervoltage lockout threshold. This function is implemented in order to prevent malfunctioning of the converter.
The undervoltage lockout function has no control of the Bypass Switch. If the Bypass Switch is enabled (EN =
VIL) there is no impact during an undervoltage condition, the Bypass Switch remains on.
Overvoltage Protection
If, for any reason, TPS61097-01 output voltage is not properly connected to the input of the voltage amplifier, the
IC cannot control the output voltage. Therefore an overvoltage protection is implemented to keep the output
voltage from exceeding the absolute maximum voltage ratings of the IC and to protect the load. For this
protection the TPS61097-01 output voltage is also monitored internally. In case it reaches the internally
programmed threshold of 6.5 V typically the voltage amplifier regulates the output voltage to this value.
If the TPS61097-01 is used to drive LEDs, this feature protects the circuit if the LED fails.
Overtemperature Protection
The device has a built-in temperature sensor which monitors the internal IC temperature. If the temperature
exceeds the programmed threshold (150 °C typical), the device stops operating. As soon as the IC temperature
has decreased below the programmed threshold, it starts operating again. There is a built-in hysteresis to avoid
unstable operation at IC temperatures at the overtemperature threshold.
