Frequently Asked Questions
What are the input and output voltage specifications of the TPS62420QDRCRQ1?
The TPS62420QDRCRQ1 operates from an input voltage range of 2.5V to 6V (nominal 3.6V). It provides two independently adjustable output channels: one rated at 600mA and another at 1000mA, both switching at a fixed 2.25MHz frequency to enable small external inductors and capacitors.
Is the TPS62420QDRCRQ1 suitable for automotive applications?
Yes. The TPS62420QDRCRQ1 carries the AEC-Q100 automotive qualification (indicated by the 'Q1' suffix), making it suitable for harsh automotive environments including infotainment systems, ADAS modules, body electronics, and instrument clusters that demand high reliability and extended temperature operation.
What package does the TPS62420QDRCRQ1 come in and what are its dimensions?
The TPS62420QDRCRQ1 is available in a 10-pin MSOP (S-PDSO-N10) surface-mount package, which offers a very small footprint ideal for space-constrained PCB designs in portable and automotive applications. The lead-free (Pb-free) construction complies with RoHS requirements.
What control method does the TPS62420QDRCRQ1 use?
The TPS62420QDRCRQ1 uses voltage-mode pulse width modulation (PWM) control, which provides stable and predictable regulation with good transient response. This control technique simplifies compensation design and ensures consistent performance across varying load conditions from light to full load.
