SEL1
FUNCTION
No Connection. Must be left unconnected.
CLK Frequency Ratio Select Input. Use SEL1 and SEL2 to set f
CLK
to f
NDRV_
frequency ratio (see Table 1).
3
CLK
Synchronizing Clock Output. Clock output with a ±10mA peak current drive that can be used to synchronize
an external PWM regulator. CLK/NDRV_ frequency has a 1x, 2x, or 4x ratio (see the
Synchronizing Clock
Output
section).

I.C.
Connect to ground. Internal function.
5
RT
Oscillator Timing Resistor Connection. Bypass RT with a 1nF capacitor to AGND. Connect a resistor from
RT to AGND to set the internal oscillator frequency.
