Description
General part information
TPS62442-Q1 Series
The TPS6244x-Q1 is a family of pin-to-pin dual 1-A, dual 2-A or 3-A, and 1-A high-efficiency and easy-to-use synchronous step-down DC/DC converters. They are based on a peak current mode control topology. The devices are designed for automotive applications such as infotainment and advanced driver assistance systems. Low resistive switches allow up to 3-A continuous output current and a total maximum output current up to 4 A at high ambient temperature. The switching frequency is externally adjustable from 1.8 MHz to 4 MHz and can also be synchronized to an external clock from 2 MHz to 4 MHz. In PWM and PFM mode, the TPS6244x-Q1 automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPS6244x-Q1 provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy.
The TPS6244x-Q1 is available as an adjustable voltage version, packaged in a VQFN package.
