The TLV61040-Q1 devices are high-frequency boost converters for automotive applications. The devices are designed for generating output voltages up to 28V from a pre-regulated low voltage rail, dual-cell NiMH/NiCd, or a single-cell Li-Ion battery, supporting input voltages from 1.8V to 20V.
The TLV61040-Q1 devices operate with a switching frequency up to 2MHz, allowing the use of small external components such as ceramic as well as tantalum output capacitors. Combined with the space-saving, 5-pin SOT-23 package, the TLV61040-Q1 devices accomplish a small overall design size. The TLV61040-Q1 device has an internal 400mA switch current limit, offering lower output voltage ripple and allowing the use of a smaller form factor inductor for lower-power applications.
The TLV61040-Q1 devices operate in a pulse frequency modulation (PFM) scheme with constant peak current control. The combination of low quiescent current (25µA typical) and the optimized control scheme enable operation of the devices at high efficiency over the entire load current range.
