The TPS61240IDRVRQ1 is a highly efficient, low input voltage boost converter designed specifically for automotive applications. This device provides a fixed 5V output voltage from input voltages as low as 0.3V, making it ideal for automotive systems requiring a stable power supply from the vehicle's battery. With its integrated 0.3Ω power MOSFET, the TPS61240IDRVRQ1 achieves high efficiency conversion of the low input voltage to the fixed 5V output, minimizing power loss and maximizing battery life. Additionally, its wide input voltage range, up to 5.5V, ensures compatibility with a variety of automotive power sources. The TPS61240IDRVRQ1 also features a power good (PG) output for power system monitoring and a low-power shutdown mode to minimize power consumption during inactive periods. This automotive-grade boost converter is supplied in a small, leadless, 10-pin SON package, making it an ideal choice for compact and space-constrained automotive applications.
