3 Description
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-touse
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.
