ASM 02-41928 REV C Terminal Connector

Product Details

Resistor timing and external clock. An external resistor from this pin to the AGND pin programs the switching

frequency between 50 kHz and 1 MHz. Driving the pin with an external clock between 300 kHz to 1 MHz

synchronizes the switching frequency to the external clock.

Soft-start programming pin. A capacitor between the SS pin and AGND pin sets soft-start time.

Output of the internal transconductance error amplifier. The feedback loop compensation network is connected

from this pin to AGND.

Error amplifier input and feedback pin for voltage regulation. Connect this pin to the center tap of a resistor divider

to set the output voltage.

Inductor current sense comparator inverting input pin. This pin is normally connected to the inductor side of the

current sense resistor.

Inductor current sense comparator non-inverting input pin. This pin is normally connected to the VIN side of the

current sense resistor.

The input supply pin to the IC. Connect VIN to a supply voltage between 4.5 and 38 V. It is acceptable for the

voltage on the VIN pin to be different from the boost power stage input, ISNS+, and ISNS pins.
