Power Ground. Connect the negative terminals of the input and output capacitors to PGND. Connect
PGND externally to SGND at a single point, typically at the return terminal of the output capacitor.
Input-Supply Voltage. Bypass IN to PGND with a ceramic capacitor of 1FF minimum value.
Active-Low Shutdown Control Input. Apply a logic-low voltage to SHDN to shut down the device.
Connect SHDN to IN for normal operation. Ensure that V SHDN is not greater than the input voltage, V IN .
SHDN is internally pulled low. The converter is disabled when SHDN is left unconnected.
Signal Ground. Connect directly to the local ground plane. Connect SGND to PGND at a single point,
typically near the return terminal of the output capacitor.
Feedback Regulation Input. Connect FB to the center tap of a resistive voltage-divider from the boost
output to SGND to set the output voltage. The FB voltage regulates to 1.23V (typ) when V CNTRL is
above 1.3V (typ) and to V CNTRL when V CNTRL is below 1.2V (typ).
Control Input for Boost Converter Output-Voltage Programmability. CNTRL allows the feedback set-point
voltage to be set externally by CNTRL when V CNTRL is less than 1.2V. Pull CNTRL above 1.3V (typ) to
use the internal 1.23V (typ) feedback set-point voltage.
Open-Drain Current-Limit Indicator. ILIM asserts low when the APD current limit has been exceeded.
Current-Limit Resistor Connection. Connect a resistor from RLIM to SGND to program the APD current-
limit threshold. When RLIM is connected to SGND, the current limit is set to 4.6mA.
Current-Monitor Output. For the MAX15059A, MOUT sources a current equal to I APD . For the
MAX15059B, MOUT sources a current equal to 1/5 of I APD .
Clamp Voltage Input. CLAMP is the external potential used for voltage clamping of MOUT.
