Offered as an automotive-qualified dc/dc converter that switches autonomously between buck and boost modes to provide a constant regulated output voltage of 5V, the TPIC74100-Q1 operates over a wide input voltage range of 1.5V to 40V. The device also minimizes EMI by implementing a clock modulator and adjustable slew rate. Additional features include a switch-mode regulator, 5V ±2% normal mode, 5V ±3% low-power or crossover mode, switching frequency of 440 kHz typical, 1A load capability, 200-mA load capability down to a 2V input, 120-mA load capability down to a 1.5V input, disable and low-power operation modes, a reset function with deglitch timer and programmable delay, and a programmable alarm function for under-voltage detection and indication. Available in a 20-pin HTSSOP PowerPAD package, pricing is $1.70 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
