It delivers up to 200 mA of output current at a fixed 50 kHz switching frequency, with the output adjustable from -1.31 V down to -15 V. The input voltage range spans 2.3 V to 16.5 V, making it suitable for systems where the available positive supply is between 3.3 V and 15 V and a clean negative rail is needed for analog signal chains, op-amp supplies, or bias circuits. ## Output configuration and temperature range The single-output regulator uses a negative output configuration and does not include synchronous rectification, so the external Schottky diode must handle the peak inductor current. The 50 kHz switching frequency keeps switching losses low but requires a larger inductor value than a higher-frequency part would. The 8-pin DIP package (0.300\" width, 7.62 mm pitch) is through-hole, which simplifies prototyping and rework compared to surface-mount alternatives. No additional compliance documentation (REACH, UL, IEC) is listed in the available record.","metaTitle":"MAX637AEPA+ Analog Devices Buck Regulator, 200mA, 8-DIP","metaDescription":"MAX637AEPA+ inverting buck regulator from Analog Devices. 200mA output, 50kHz switching, -1.31V to -15V adjustable output.
