VQFN-HR (RQR)-14-6.21 mm² 2.7 x 2.3
The TPS6244x is a family of pin-to-pin dual 1-A, dual 2-A, and 3-A/1-A high-efficiency and easy-to-use synchronous step-down DC/DC converters. The device family is based on a peak current mode control topology. The devices are designed for industrial applications such as motor drives and robotics. Low resistive switches allow up to 3-A continuous output current and 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 in the same frequency range. In PWM/PFM mode, the TPS6244x automatically enters power save mode at light loads to maintain high efficiency across the whole load range. The TPS6244x provides a 1% output voltage accuracy in PWM mode, which helps design a power supply with high output voltage accuracy.
The TPS6244x is available as an adjustable voltage version, packaged in a VQFN package.
