FUNCTIONAL DESCRIPTION

STANDBY

The SBRC controller can be switched into standby mode separately by grounding STBY pin.

UNDERVOLTAGE LOCK OUT (UVLO)

For undervoltage lock out (UVLO), the TPS5124 monitors VREF5 voltage. When the VREF5 voltage decreases

below about 4.1 V, the output stages of both SBRC are turned off. This state is not latched and the operation

recovers immediately after the input voltage becomes higher than about 4.2 V again. The typical hysteresis

voltage is 40 mV.

PHASE INVERTER

The SBRC (CH2) of the TPS5124 operates in the same phase as the internal triangular oscillator output while

the SBRC (CH1) operates 180_ out of phase. When the SBRC (CH1) and the SBRC (CH2) share the same input

power supply, the TPS5124 reduces input current ripple and enables the input capacitor value smaller.

OSCILLATOR

TPS5124 has a triangle oscillator generator internal to the device. The oscillation frequency is set by the size

of the capacitor connected to the CT pin.
