WPMDB1400362Q / 171040302 3 MagI C Power Module VDRM Variable Step Down Regulator Module 2.95 6V / 4A / 0.8 3.6V Output DESCRIPTION FEATURES 3 The VDRM 1710x0302 series of the MagI C Power Peak efficiency up to 96% Module family provide a fully integrated DC-DC power Current capability up to 4A supply including the switching regulator with integrated Input voltage range: 2.95 to 6V MOSFETs, compensation and shielded inductor in one Output voltage range: 0.8 to 3.6V package. These modules require as few as 4 external Continuous output power: 14.4W components. Integrated shielded inductor Low output voltage ripple: 5mV typ. The 171040302 offers high efficiency and delivers up to Reference accuracy over temperature: 1% max. 4A of output current. It operates with an input voltage Adjustable switching frequency: 0.5 to 2 MHz from 2.95 to 6V and is designed for fast transient Current Mode control response. Synchronous operation Forced continuous mode under light load It is available in a standard industrial high power density Undervoltage lockout protection (UVLO) QFN package (11mm x 9mm x 2.8mm) with very good Adjustable soft-start and voltage tracking thermal performance. Frequency synchronization with external clock Sequencing This module has an on-board protection circuitry to guard Thermal shutdown against thermal overstress and electrical damage Short circuit protection featuring thermal shutdown, over-current, short-circuit, overvoltage and undervoltage protections. Cycle-by-cycle current limit Output overvoltage protection Output undervoltage and overvoltage Power Good Pin compatible with 171020302 & 171060302 TYPICAL APPLICATIONS Operating ambient temperature up to 85C No derating within the operating temperature range Point-of-load DC-DC applications from 5V and 3.3V Operating junction temp. range: -40 to 125C rails UL94V-0 package material Industrial, test & measurement, medical applications Complies with EN55022 class B radiated emissions Communication infrastructure standard System power supplies DSPs, FPGAs, MCUs and MPU supply I/O interface power supply High density distributed power systems TYPICAL CIRCUIT DIAGRAM we-online.com Wrth Elektronik eiSos GmbH & Co.
