The SMB113A/SMB117 power managers offer four identical channels of PWM dc/dc step-down (buck) converters that are digitally programmable for output characteristics and monitoring, including voltage output levels to ±1.5% accuracy. The SMB113A operates at a switching frequency of 800 kHz, whereas the SMB117’s switching frequency is 400 kHz.
Features include a 2.7 to 6-V input and complete power system diagnostics, including input and output monitoring for undervoltage and overvoltage conditions, as well as a reset/healthy monitor. Operating temperature ranges from 0 to 70C and from -40 to 85C, and housing is in 32-pad QFN packages. (From $2.26 ea/1,000–available now.)
