LSM2-T/30-D12 Series www.murata-ps.com DOSA-SMT, 30A POL DC/DC Converters TTypical unypical unitit FEATURES DESCRIPTIONDESCRIPTION Non-isolated Point-of-Load (POL) converter, ideal Todays high performance CPU and programma- no additional external components required, for mixed voltage systems ble logic devices demand superior performance stable no-load operation, up to 10,000 F output Optimized for CPUs, DSPs and programmable logic from their power source. The LSM2-T/30-D12 load capacitance and no reverse conduction. - FPGAs, ASICs series DC/DC converters offer up to 30 Amps System functions offer a remote On/Off 30 Amps maximum output current continuous output power with a user-selectable control, two additional ground pins (optional) output of 0.8 to 3.6 Volts. 25 Amps output is and a load Sense input. These converters meet User-selectable output voltage, 0.8Vdc to 5.0Vdc via trim resistor or voltage input available up to 5.0 VOUT. This tiny converter is agency standards UL/EN 60950-1, CAN/CSA- ideal for applications with an input range of C22.2 60950-1, IEC 60950-1, 2nd edition, and Wide input range 6Vdc to 14Vdc (Vout <3.6V) 6 to 14 Volts DC.
