Texas Instruments has introduced the TPIC74100-Q1, an automotive-qualified dc/dc power management integrated circuit that switches autonomously between buck and boost modes to provide a constant regulated output voltage of 5 V. The device operates over a 1.5 V to 40 V input voltage range and is said to eliminate the need for external components and to minimize electromagnetic interference (EMI) by implementing a clock modulator and adjustable slew rate.
