DETAILED DESCRIPTION
Oscillator Frequency
Voltage Reference
Enable (ENA) and Internal Slow Start
SLVS911 – MARCH 2009................................................................................................................................................................................................... www.ti.com
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.
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.
The ENA pin provides electrical on/off control of the regulator. Once ENA voltage exceeds the threshold voltage,
the regulator starts operation and the internal slow start begins to ramp. If ENA 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 activates the shutdown mode. The quiescent current
of the TPS5430 in shutdown mode is typically 18
A.
