Input supply voltage for the output driver section. Input voltage range is 2.7 V to 6V
Not Used
The gate drive output for the high-side p-channel MOSFET. The p-channel MOSFET is the main switch for
buck topology and the synchronous rectifier for the boost topology.
Logic high = PWM mode, logic low = PSM mode. In PSM mode, synchronous rectification is disabled.
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization. If
not used, the pin must be connected to V
DD
, or logic high.
Low power controller ground
1.3-V reference. Decoupled with 0.1-μF capacitor
Output voltage feedback connected to the inverting input of an error amplifier.
Error amplifier output for external compensation network.
External resistor to determine the switching frequency.
Input supply voltage for the analog circuit. Input voltage range is 2.7 V to 6 V.
Direct output voltage sense
Power ground for output drive stage
The gate drive output for the low-side n-channel MOSFET. The n-channel MOSFET is the synchronous
rectifier for the buck topology and the main switch for the boost topology.
