The LMR36503RS3QRPERQ1 from Texas Instruments is an automotive-qualified synchronous buck converter designed for efficiency and size optimization. It supports a wide input voltage range from 3 V to 65 V and can deliver up to 0.3 A of output current.
This device features a fixed output voltage capability, current mode control, and a switching frequency adjustable from 200 kHz to 2.2 MHz. It boasts a low quiescent current of 4 µA, making it suitable for light load efficiency requirements. The converter includes features such as enable, over-current protection, power good, pre-bias start-up, and soft start.
Packaged in a compact 2 mm x 2 mm VQFN-HR (RPE) package with wettable flanks, the LMR36503RS3QRPERQ1 is designed for surface mounting. Its operating temperature range is -40°C to 150°C (junction temperature). The device is AEC-Q100 qualified for automotive applications and is functional safety-capable, with documentation available to aid system design.
EMI features include low parasitic Hotrod packaging and spread spectrum control, compatible with CISPR 25 standards. This converter is optimized for applications requiring a small solution size and low component count.
