MAXM15062/MAXM15063/ MAXM15064 4.5V to 60V, 300mA Himalaya uSLIC Step-Down Power Module General Description The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM15062/MAXM15063/MAXM15064 are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, compensation components, and inductor that operate over a wide input-voltage range. The modules operate from 4.5V to 60V input and deliver up to 300mA output current. The MAXM15062 and MAXM15063 are fixed 3.3V and 5V output modules respectively. The MAXM15064 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.

The modules deliver an output current up to 300mA. The MAXM15062 and MAXM15063 are fixed 3.3V and 5V output modules respectively. The MAXM15064 is an adjustable output (0.9V to 5V) module. When EN/UVLO and VCC UVLO are ascertained, an internal power-up sequence ramps up the error-amplifier reference, resulting in an output-voltage soft-start. The FB pin monitors the output voltage through a resistordivider. The RESET pin transitions to a high-impedance state 2ms after the output voltage reaches 95.5% of regulation. The devices select either PFM or forcedPWM mode depending on the state of the MODE pin at power-up. By pulling the EN/UVLO pin to low, the devices enter shutdown mode and consumes only 2.2μA (typ) of standby current. The modules use an internally compensated, fixed-fre­ quency, current-mode control scheme. On the rising edge of an internal clock, the high-side pMOSFET turns on. An internal error amplifier compares the feedback voltage to a fixed internal refer­ence voltage and generates an error voltage. The error voltage is compared to a sum of the current-sense voltage and a slope-compensation voltage by a PWM comparator to set the on-time. During the on-time of the pMOSFET, the inductor current ramps up. For the remainder of the switching period (off-time), the pMOSFET is kept off and the low-side nMOSFET turns on. During the off-time, the inductor releases the stored energy as the inductor current ramps down, providing current to the output. Under over­load conditions, the cycle-by-cycle current-limit feature limits the inductor peak current by turning off the high-side pMOSFET and turning on the low-side nMOSFET. Mode Selection (MODE) The logic state of the MODE pin is latched after VCC and EN/UVLO voltages exceed respective UVLO rising thresholds and all internal voltages are ready to allow LX switching. If the MODE pin is unconnected at power-up, the part operates in PFM mode at light loads. If the MODE pin is grounded at power-up, the part operates in constant-frequency PWM mode at all loads. State changes on the MODE pin are ignored during normal operation. PWM Operation In PWM mode, the module output current is allowed to go negative. PWM operation is useful in frequency sensitive applications and provides fixed switching frequency www.maximintegrated.com 4.5V to 60V, 300mA Himalaya uSLIC Step-Down Power Module operation at all loads. However, PWM-mode of operation gives lower efficiency at light loads compared to PFMmode of operation. PFM Operation PFM mode operation disables negative output current from the module, and skips pulses at light loads for better efficiency. In PFM mode, the module output current is forced to a fixed peak of 130mA in every clock cycle until the output voltage rises to 102.3% of the nominal value. Once the output voltage reaches 102.3% of the nominal value, the high-side switch is turned off and the low-side switch is turned on. Once the module output current hits zero cross, LX goes to a high-impedance state and the module enters hibernate operation until the load current discharges the output voltage to 101.1% of the nominal value. Most of the internal blocks are turned off in hibernate operation to save quiescent current. When the output voltage falls below 101.1% of the nominal value, the module comes out of hibernate operation, turns on all internal blocks, and commences the process of delivering pulses of energy until the output voltage reaches 102.3% of the nominal value. The module naturally comes out of PFM mode and serves load requirements when the module output demands more than 130mA peak. The advantage of PFM mode is higher efficiency at light loads because of lower quiescent current drawn from supply. Internal 5V Regulator An internal regulator provides a 5V nominal supply to power the internal functions and to drive the power MOSFETs. The output of the linear regulator (VCC) should be bypassed with a 1μF ceramic capacitor to GND. The VCC regulator dropout voltage is typically 150mV. An undervoltage lockout circuit that disables the buck converter when VCC falls below 3.8V (typ). The 400mV, VCC-UVLO hysteresis prevents chattering on power-up and power-down. Enable/Undervoltage Lockout (EN/UVLO), Soft-Start When EN/UVLO voltage is above 1.215V (typ), the device’s internal error-amplifier reference voltage starts to ramp up. The duration of the soft-start ramp is 4.1ms (typ), allowing a smooth increase of the output voltage. Driving EN/UVLO low disables both power MOSFETs, as well as other internal circuitry, and reduces VIN quiescent current to below 2.2μA. EN/UVLO can be used as an input-voltage UVLO adjustment input. An external voltage-divider between VIN and EN/UVLO to GND adjusts the input voltage at which the device turns on or turns off. If input UVLO programming is not desired, connect EN/ UVLO to VIN (see the Electrical Characteristics table for EN/UVLO rising and falling threshold voltages).

RESET goes high impedance 2ms after the output rises above 95.5% of its nominal set value and pulls low when the output voltage falls below 92% of the set nominal regulated voltage. RESET asserts low during the hiccup timeout period. The devices are capable of soft-start into a prebiased output, without discharging the output capacitor in both the PFM and forced-PWM modes. Such a feature is useful in applications where digital integrated circuits with multiple rails are powered. Overcurrent Protection (OCP)/Hiccup Mode The MAXM15062/MAXM15063/MAXM15064 are provided with a robust overcurrent protection (OCP) scheme that protects the modules under overload and output short-circuit conditions. The power module measures and limits peak inductor current. When overcurrent is detected in the inductor, or if the FB node goes below 64.5% of its nominal regulation threshold, the module enters hiccup mode of operation. In hiccup mode, the module is protected by suspending switching for a hiccup timeout period of 131ms (typ). Once the hiccup timeout period expires, soft-start is attempted again. Hiccup mode of operation ensures low power dissipation under output overload or short-circuit conditions. Once the hiccup timeout period expires, soft-start is attempted again. The MAXM15062/3/4 are designed to support a maximum load current of 300mA. The inductor ripple current is calculated as follows: ∆I  VIN − VOUT − 4.85 × I OUT   VOUT + 3.05 × I OUT   ×  L × f SW    VIN − 1.8 × I OUT  Thermal overload protection limits the total power dissipation in the device. When the junction temperature exceeds +166°C, an on-chip thermal sensor shuts down the device, turns off the internal power MOSFETs, allowing the device to cool down. The thermal sensor turns the device on after the junction temperature cools by 10°C. Input-Voltage Range The minimum and maximum operating input voltages for a given output voltage should be calculated as follows: = VIN(MIN) VOUT + (I OUT × 3.05) D MAX VIN(MAX) = + (I OUT × 1.8) VOUT t ON(MIN) × f SW where: VOUT = Steady-state output voltage, IOUT = Maximum load current, fSW = Worst-case switching frequency(535000 Hz), DMAX = Maximum duty cycle (0.89), tON(MIN) = Worst-case minimum controllable switch ontime (130ns). Also, for duty cycle > 0.5; VIN(MIN) > ((4.27 × VOUT) − 9.76) For MAXM15062, VIN(MIN) = 5.5V, VIN(MAX) = 48V For MAXM15063, VIN(MIN) = 12V, VIN(MAX) = 60V Selection of Input Capacitor Where: VOUT = Steady-state output voltage VIN = Operating input voltage for given VOUT fSW = Switching Frequency L = Power module output inductance (33µH ±30%) IOUT = Required output (load) current The following condition should be satisfied at the desired load current, IOUT. I OUT + www.maximintegrated.com ∆I < 0.49 2 The input filter capacitor reduces peak currents drawn from the power source and reduces noise and voltage ripple on the input caused by the converter’s switching. The input capacitor RMS current requirement (IRMS) is defined by the following equation: = IRMS I OUT(MAX) × VOUT × (VIN − VOUT ) VIN where, IOUT(MAX) is the maximum load current. IRMS has a maximum value when the input voltage equals twice the output voltage (VIN = 2 x VOUT). So, I OUT(MAX) IRMS(MAX) = 2 Maxim Integrated │  17 MAXM15062/MAXM15063/ MAXM15064 Choose an input capacitor that exhibits less than a +10°C temperature rise at the RMS input current for optimal long-term reliability. Use low-ESR ceramic capacitors with high-ripple-current capability at the input. X7R capacitors are recommended in industrial applications for their temperature stability. Calculate the input capacitance using the following equation: C IN = I OUT(MAX) × D MAX × (1 − D MAX ) f SW × ∆VIN where: DMAX = Maximum duty cycle(0.89), fSW = Switching frequency, ∆VIN = Allowable input-voltage ripple. Selection of Output Capacitor Small ceramic X7R-grade capacitors are sufficient and recommended for output-voltage generation. The output capacitor has two functions. It provides smooth voltage and, stores sufficient energy to support the output voltage under load transient conditions and stabilizes the device’s internal control loop. Usually the output capacitor is sized to support a step load of 50% of the maximum output current in the application, such that the output-voltage deviation is less than 3%. Required output capacitance can be calculated from the following equation: 30 C OUT = VOUT where COUT is the output capacitance in μF and VOUT is the output voltage. Derating of ceramic capacitors with DC-voltage must be considered while selecting the output capacitor.

Set the voltage at which the device turns on with a resistive voltage-divider connected from VIN to GND (see Figure 1). Connect the center node of the divider to EN/UVLO. Choose R1 to be 3.3MΩ (max), and then calculate R2 as follows: R1× 1.215 R2 = VINU − 1.215 where VINU is the voltage at which the device is required to turn on. If the EN/UVLO pin is driven from an external signal source, a series resistance of minimum 1kΩ is recommended to be placed between the signal source output and and the EN/UVLO pin, to reduce voltage ringing on the line. Output-Voltage Setting The MAXM15064 output voltage can be programmed from 0.9V to 5V. Set the output voltage by connecting a resistor-divider from output to FB to GND (see Figure 2). Choose R4 less than or equal to 75kΩ and calculate R3 with the following equation: V  R3 = R4 ×  OUT − 1 0.9   Connect FB of MAXM15062 and MAXM15063 directly to VOUT for feedback control.

Power Dissipation The power dissipation inside the module leads to increase in the junction temperature of the MAXM15062/ MAXM15063/MAXM15064. The power loss inside the module at full load can be estimated as follows: 1  PLOSS = POUT ×  − 1 η  Where η is the efficiency of the power module at the desired operating conditions. The junction temperature (TJ) of the module can be estimated at any given maximum ambient temperature (TA) from the following equation: T= J T A + θ JA × PLOSS  www.maximintegrated.com For the MAXM15062/MAXM15063/MAXM15064 evaluation board, the thermal resistance from junction-toambient (θJA) is 41.56°C/W. Operating the module at junction temperatures greater than +125°C degrades operating lifetimes. An EESIM model is available for the MAXM15062/MAXM15063/MAXM15064 to simulate efficiency and power loss for the desired operating conditions.
