Power good output pin. PGOOD is an open-drain output. Connect a pull
up resister to 5V. Current capability is 6mA.
SMPS current limit threshold setting pin. Connect resistor form this pin to
ground to set threshold for both overcurrent limit and negative overcurrent
limit. Set the OCL trip voltage is V
SMPS Enable pin.
SMPS voltage feedback input
Switch frequency / Mode selection pin. Connect a resistance to selection
switching frequency. Besides, as the resistance connects to GND is
auto-skip mode, or connecting to PGOOD pin select PWM mode.
Low side N-MOS gate driver output. Drive voltage is V5IN voltage.
Power supply input.
High side N-MOS gate driver return. Also used for on time generation and
output discharge.
High side N-MOS gate driver output. Drive voltage corresponds to VBST
to LX voltage.
Supply input for high side N-MOS gate driver (Boost terminal). Connect
capacitor from this pin to LX. An internal MOSFET is connected between
V5IN to this pin. Designer can add external Schottky diode if forward drop
is critical to drive the power N-MOS.
Ground.
