This switcher frequency selection pin can be adjusted by connecting external
resistor RF to the FREQ pin. The default switching frequency (FREQ pin left open or
tied to VDDI) is set to 300kHz.
Buck controller error amplifier inverting input.
Output voltage of the buck converter. Input pin of the switching regulator power
sequence control circuit.
Buck regulator power input. Drain of the high side power MOSFET.
Buck regulator switching node. This pin is connected to the inductor.
Analog ground of the IC, thermal heatsinking.
Buck regulator power ground.
Drain of the internal boost regulator power MOSFET.
Internal boost regulator output voltage. The internal boost regulator provides a 20mA
output current to supply the drive circuits for the integrated power MOSFETs and the
external N-channel power MOSFET of the linear regulator. The voltage at the VBST
pin is 7.75V (nominal).
Bootstrap capacitor input.
