Function
1VREF2
Internal 2 V high accuracy voltage reference. It can deliver 50
μA. Loading
VREF2 can affect FB and output accuracy. Bypass to GND with a 100 nF
capacitor.
2TON
Frequency selection pin. It provides a selectable switching frequency,
allowing three different values of switching frequencies for the switching
sections.
3
VCC
Controller supply voltage input. Bypass to GND with a 1
μF capacitor.
4EN_LDO
Enable input for the linear regulator. The LDO is enabled if
EN_LDO is > 1.6 V and is disabled if EN_LDO < 1 V.
5VREF3
Internal 3.3 V high accuracy voltage reference. It can deliver 5 mA if
bypassed to GND with a 10 nF capacitor. If not used, it can be left floating.
6VIN
Device supply voltage pin. VIN is used in the on-time generators of the two
switching controllers. VIN is also used to power the linear regulator when the
switchover function is not active. Connect VIN to the battery input and
bypass with a 1 F capacitor.
