TI Buck-Boost DC/DC Converter Widens Input Voltage Range for Automotive Applications
DALLAS (April 11, 2007) - Texas Instruments Incorporated (TI) (NYSE: TXN) introduced today an automotive-qualified DC/DC power management integrated circuit (IC) that switches autonomously between buck and boost modes to provide a constant regulated output voltage of 5 V. The TPIC74100-Q1 operates over a wide input voltage range of 1.5 V to 40 V and simplifies design by eliminating the need for external components. The device also minimizes electro-magnetic interference (EMI) in the system by implementing a clock modulator and adjustable slew rate. See www.ti.com/sc07073.
Additional key features include the following:
o Switch-mode regulator
o 5 V ± 2%, normal mode
o 5 V ± 3%, low-power or crossover mode
o Switching frequency of 440 kHz (typical) is outside of the AM frequency band
o Input Operating Range, 1.5 V to 40 V, (Vdriver)
o 1-A Load-Current Capability
o 200-mA Load-Current Capability Down to 2 V Input (Vdriver)
o 120-mA Load-Current Capability Down to 1.5 V Input (Vdriver)
o Disable and low-power operation modes to optimize power savings
o Reset function with deglitch timer and programmable delay provides increased reliability in the system
o Programmable alarm function for undervoltage detection and indication
o Thermally-enhanced package for efficient heat management
