171960501 3 MagI C Power Module VDMM Variable Step Down MicroModule 2.7V 5.5V / 0.6A / 0.6V 5.5V Output DESCRIPTION FEATURES 3 The VDMM 171960501 MagI C MicroModule provides a Peak efficiency up to 96% fully integrated DC-DC power supply including the Current capability up to 0.6A controller IC with integrated MOSFETs, compensation and Input voltage range: 2.7V to 5.5V shielded inductor in one package. Output voltage range: 0.6V to 5.5V 30 A typical quiescent current The 171960501 offers high efficiency and delivers up to Integrated shielded inductor 0.6A of output current. It operates with an input voltage Integrated input and output auxiliary capacitors from 2.7V to 5.5V and is designed for small solution size. Low output voltage ripple: 10mV typ. Output voltage accuracy over temperature: 2% max. The selectable forced PWM or PFM/PWM mode allows for Fixed switching frequency: 2.25 MHz the choice between high efficiency and low output voltage Voltage Mode control ripple at light load. Synchronous operation Selectable forced PWM or PFM/PWM mode It is available in an LGA-6EP package (3.2 x 2.5 x 1.6mm). Undervoltage lockout (UVLO) Internal soft-start This MicroModule has integrated protection circuitry that Thermal shutdown guards against thermal overstress with thermal shutdown Short-circuit protection and protects against electrical damage using overcurrent, Cycle-by-cycle current limit short-circuit and undervoltage protections. RoHS und REACh compliant Operating ambient temperature up to 85C TYPICAL APPLICATIONS No output current derating within the operating General point of load power supply for low power temperature range systems Operating junction temp. range: -40 to 125C Replacement of linear regulators Complies with EN55032 (CISPR-32) class B radiated DSP and FPGA power supply auxiliary voltages emissions standard Portable instruments Battery powered equipment TYPICAL CIRCUIT DIAGRAM 4 1 V VOUT IN VIN V OUT Module 5 R C FBT FF EN 3 C C IN 2 FB OUT MODE R FBB PGND PGND EP 6 GND GND we-online.com Wrth Elektronik eiSos GmbH & Co.

Place output capacitor(s) as close as possible to VOUT and VOUT 1 Power GND. For best thermal performance use copper plane(s) at this pin. Forced PWM or PFM/PWM mode selection pin. Setting this pin high, the forced PWM mode is selected for any load current. Setting this pin low, PFM/PWM is MODE 2 Input selected, with the transition happening automatically between the two operations according to the load. This pin must not be left floating. Feedback pin. This pin must be connected to the external resistor divider FB 3 Input (between VOUT and GND) to adjust the output voltage. Input voltage. Place the input capacitor(s) as close as possible to VIN and VIN 4 Power GND. Enable pin. Setting this pin high enables the device, while setting this pin low EN 5 Input shuts down the device. This pin must not be left floating. we-online.com Wrth Elektronik eiSos GmbH & Co. KG Data Sheet Rev. 3.0 April 2020 2/40
