Operating over a wide input voltage range of 1.5 to 40 V, the TPIC74100-Q1 buck/boost dc/dc converter switches autonomously between buck and boost modes to provide a constant regulated output voltage of 5 V. The part provides 440-kHz typ switching frequency, 1-A load current capability, and 200-mA load-current capability down to 2-V input (Vdriver).
The device also minimizes EMI in the system by implementing a clock modulator and adjustable slew rate. Housed in 20-pin HTSSOP PowerPAD packages, the part features disable and low-power operation modes, reset function with deglitch timer and programmable delay, and programmable alarm function for undervoltage detection and indication.
