FUNCTION
Compensation Pin for Error Amplifier. Connect a series RC from COMP to ground. See the Loop
Compensation section for component selection guidelines.
Feedback Pin. The FB regulation voltage is 1.24V nominal. Connect an external resistive voltage-divider
between the step-up regulator ’s output (V OUT ) and AGND, with the center tap connected to FB. Place the
divider close to the IC and minimize the trace area to reduce noise coupling. Set V OUT according to the
Output Voltage Selection section.
Shutdown Control Input. Drive SHDN low to turn off the MAX17062.
Power Ground. Connect pins 4 and 5 directly together.
Switch Pin. LX is the drain of the internal MOSFET. Connect the inductor/rectifier diode junction to LX and
minimize the trace area for lower EMI. Connect pins 6 and 7 together.
Supply Pin. Bypass IN with a minimum 1μF ceramic capacitor directly to AGND.
Frequency-Select Input. When FREQ is low, the oscillator frequency is set to 640kHz. When FREQ is high,
the frequency is 1.2MHz. This input has a 6 μA pulldown current.
Soft-Start Control Pin. Connect a soft-start capacitor (C SS ) to this pin. Leave open for no soft-start. The soft-
start capacitor is charged with a constant current of 4 μA. Full current limit is reached when the voltage of
10
SS
SS pin is charged to 1.5V, which is the current-limit time, t = 2.4
10 5 C SS . The soft-start capacitor is
discharged to ground when SHDN is low. When SHDN goes high, the soft-start capacitor is charged to 0.4V,
after which soft-start begins.
