APPLICATION INFORMATION
FUNCTIONAL BLOCK DIAGRAM
DETAILED DESCRIPTION
Oscillator Frequency
The internal free running oscillator sets the PWM switching frequency at 500 kHz. The 500-kHz switching
frequency allows less output inductance for the same output ripple requirement resulting in a smaller output
inductor.
Voltage Reference
The voltage reference system produces a precision reference signal by scaling the output of a temperature
stable bandgap circuit. The bandgap and scaling circuits are trimmed during production testing to an output of
1.221 V at room temperature.
Enable (ENA) and Internal Slow Start
The ENA pin provides electrical on/off control of the regulator. Once the ENA pin voltage exceeds the threshold
voltage, the regulator starts operation and the internal slow start begins to ramp. If the ENA pin voltage is pulled
below the threshold voltage, the regulator stops switching and the internal slow start resets. Connecting the pin
to ground or to any voltage less than 0.5 V disables the regulator and activate the shutdown mode. The
quiescent current of the TPS5410 in shutdown mode is typically 18
μA.
