Wide Vin Low Noise Triple Output Step Down Converter Reference Design
Texas Instruments
The reference design PMP9462 is a single input step-down converter with three low-noise outputs. The module uses LM43603: a synchronous step-down DC-DC converter capable of driving up to 3A of load current from an input voltage ranging 7V to 36V. The 5V output from LM43603 enables the LM26420 which further steps down this voltage to produce 1.8V and 2.5V outputs: capable of driving 1A load current each. This power supply is suitable for applications that require multiple outputs from a single input DC voltage. It provides good regulation performance over an input voltage range of 7V to 36V.
