pin FuncTions fSET (Pin B12):
Frequency set internally to 800kHz in
SGND (Pins D9, H12):
Signal Ground Pins. These pins continuous conducting mode at light load. An external connect to PGND at output capacitor point. See Figure 17. resistor can be placed from this pin to ground to increase
COMP (Pins A11, D11):
Current Control Threshold and frequency. See the Applications Information section for Error Amplifier Compensation Point. The current com- frequency adjustment. parator threshold increases with this control voltage. The
VFB (Pin F12):
The Negative Input of the Error Amplifier. voltage ranges from 0V to 2.4V with 0.7V corresponding Internally, this pin is connected to VOUT with a 60.4k preci- to zero sense voltage (zero current). sion resistor. Different output voltages can be programmed
PGOOD (Pin G12):
Output Voltage Power Good Indicator. with an additional resistor between the VFB and SGND pins. Open-drain logic output that is pulled to ground when the See the Applications Information section. output voltage is not within ±10% of the regulation point,
MARG0 (Pin C12):
LSB Logic Input for the Margining after a 25µs power bad mask timer expires. Function. Together with the MARG1 pin, the MARG0 pin
RUN (Pins A10, B9):
Run Control Pins. A voltage above will determine if a margin high, margin low, or no margin 1.9V will turn on the module, and below 1V will turn off state is applied. The pin has an internal pulldown resistor the module. A programmable UVLO function can be ac- of 50k. See the Applications Information section. complished with a resistor divider from VIN to ground. See
MARG1 (Pins C11, D12):
MSB Logic Input for the Margin- Figure 1. This pin has a 5.1V Zener to ground. Maximum ing Function. Together with the MARG0 pin, the MARG1 pin voltage is 5V. Limit current into the RUN pin to less pins will determine if a margin high, margin low, or no than 1mA. margin state is applied. The pins have an internal pul -down
