The MAXM15062/MAXM15063/MAXM15064are a family of high-efficiency, synchronous step-downDC-DC modules with integrated controller, MOSFETs,compensation components, and inductor that operateover a wide input-voltage range. The modules operate from 4.5V to 60V input and deliver up to 300mAoutput current. The MAXM15062 and MAXM15063 arefixed 3.3V and 5V output modules respectively. TheMAXM15064 is an adjustable output (0.9V to 5V) module. The modules significantly reduce design complexity,manufacturing risks, and offer a true plug and play power/supply solution, reducing time-to-market.The MAXM15062/3/4 modules employ peak-currentmode control architecture. To reduce input inrush current,the modules offer a fixed 4.1ms soft-start time.The MAXM15062/3/4 modules are available in a low profile, compact 10-pin, 2.6mm 3mm 1.5mm, uSLIC package.ApplicationsBenefits and Features Easy to Use Wide 4.5V to 60V Input Adjustable 0.9V to 5V Output Fixed 3.3V and 5V Output (MAXM15062 andMAXM15063) 1.5% Feedback Accuracy Up to 300mA Output-Current Internally Compensated All Ceramic Capacitors High Efficiency Selectable PWM- or PFM-Mode of Operation Shutdown Current as Low as 2.2μA (typ) Flexible Design Internal Soft-Start and Prebias Startup Open-Drain Power Good Output (RESET Pin) Programmable EN/UVLO Threshold Robust Operation Hiccup Overcurrent Protection Overtemperature Protection -40 C to 125 C Ambient Operating Temperature/-40 C to 150 C Junction Temperature Rugged Complies with CISPR22(EN55022) Class BConducted and Radiated Emissions Passes Drop, Shock, and Vibration Standards:JESD22-B103, B104, B111 Industrial Sensors and Encoders 4-20mA Current-Loop Powered Sensors LDO Replacement HVAC and Building Control Battery-Powered EquipmentOrdering Information appears at end of data sheet.

MAXM15062/MAXM15063/MAXM15064Detailed DescriptionThe MAXM15062/MAXM15063/MAXM15064 are a family of high-efficiency, synchronous step-down DC-DCmodules with integrated controller, MOSFETs, compensation components, and inductor that operate over a wideinput-voltage range. The modules deliver an output current up to 300mA. The MAXM15062 and MAXM15063are fixed 3.3V and 5V output modules respectively. TheMAXM15064 is an adjustable output (0.9V to 5V) module. When EN/UVLO and VCC UVLO are ascertained, aninternal power-up sequence ramps up the error-amplifierreference, resulting in an output-voltage soft-start.The FB pin monitors the output voltage through a resistordivider. The RESET pin transitions to a high-impedancestate 2ms after the output voltage reaches 95.5% ofregulation. The devices select either PFM or forcedPWM mode depending on the state of the MODE pin atpower-up. By pulling the EN/UVLO pin to low, the devicesenter shutdown mode and consumes only 2.2μA (typ) ofstandby current.The modules use an internally compensated, fixed-fre quency, current-mode control scheme. On the rising edgeof an internal clock, the high-side pMOSFET turns on.An internal error amplifier compares the feedback voltage to a fixed internal refer ence voltage and generatesan error voltage. The error voltage is compared to a sumof the current-sense voltage and a slope-compensationvoltage by a PWM comparator to set the on-time. Dur
