FUNCTION
Step-Up Converter Compensation Node. Connect a series resistor-capacitor from this pin to GND for
compensating the converter control loop. This pin is actively driven to GND in shutdown, overload,
and thermal limit. See the Step-Up Compensation section.
Step-Up Converter Feedback Input. The feedback threshold is 1.25V. This pin is high impedance in
shutdown.
Step-Up Converter On/Off Control. Logic high = on. All other ON_ pins are locked out until 1024 OSC
cycles after the step-up DC-to-DC converter output has reached its final value. This pin has an
internal 330k ? pulldown resistance to GND.
Open-Drain, Active-Low, Short-Circuit Flag Output. SCF goes open when overload protection occurs
and during startup. SCF can drive high-side PFET switches connected to one or more outputs to
completely disconnect the load when the channel turns off in response to a logic command or an
overload. See the Status Outputs ( SDOK , AUX1OK , SCF) section.
Open-Drain, Active-Low, Power-OK Signal for AUX1 Controller. AUX1OK goes low when the AUX1
controller has successfully completed soft-start. AUX1OK goes high impedance in shutdown,
overload, and thermal limit.
Open-Drain, Active-Low, Power-OK Signal for Step-Down Converter. SDOK goes low when the step-
down has successfully completed soft-start. SDOK goes high impedance in shutdown, overload, and
thermal limit.
Oscillator Control. Connect a timing capacitor from OSC to GND and a timing resistor from OSC to
PVSU (or other DC voltage) to set the oscillator frequency between 100kHz and 1MHz. See the
Setting the Switching Frequency section. This pin is high impedance in shutdown.
Power Ground. Connect all PG_ pins to GND with short wide traces as close to the IC as possible.
Step-Up Converter Switching Node. Connect to the inductor of the step-up converter. LXSU is high
impedance in shutdown.
Power Output of the Step-Up DC-to-DC Converter. PVSU can also power other converter channels.
Connect PVSU and PV together.
Power Ground. Connect all PG_ pins to GND with short wide traces as close to the IC as possible.
Main Converter Switching Node. Connect to the inductor of the main converter (can be configured as
a step-up or step-down by SUSD). LXM is high impedance in shutdown.
When SUSD = PVSU, the main converter is configured as a step-up and PVM is the main output.
When SUSD = GND, the main is configured as a step-down and PVM is the power input.
AUX2 Controller On/Off Input. Logic high = on; however, turn-on is locked out until 1024 OSC cycles
after the step-up has reached regulation. This pin has an internal 330k ? pulldown resistance to GND.
AUX2 Controller Compensation Node. Connect a series resistor-capacitor from this pin to GND to
compensate the converter control loop. This pin is actively driven to GND in shutdown, overload, and
thermal limit. See the AUX Compensation section.
