WQFN-FCRLF (RZT)-20-9.36 mm² 3.6 x 2.6
The LM654x0-Q1 are a family of automotive buck converters designed for high efficiency, high power density, and ultra-low electromagnetic interference (EMI). The converters operate over a wide input voltage range of 3V to 36V (42V tolerant) The LM654x0-Q1 is dual phase capable by simply connecting the compensated error signal between the primary and secondary device. The LM654x0-Q1 comes with pin selectable fixed output voltages of 3.3V and 5V or in adjustable configuration. The low EMI operation is enabled with minimized loop inductance and optimized switch node slew rate. The current-mode control architecture with a 30ns typical minimum on-time allows high conversion ratios at high frequencies coupled with a fast transient response and excellent load and line regulation.
