General Description

The RTQ2104 is a 3A, high-efficiency, current mode

synchronous step-down converter which is optimized for

automotive applications. The device operates with input

voltages from 3V to 36V and is protected from load dump

transients up to 42V, eases input surge protection design.

The device can program the output voltage between 0.8V

to VIN. The low quiescent current design with the integrated

low RDS(ON) power MOSFETs achieves high efficiency over

the wide load range. The peak current mode control with

simple internal compensation allows the use of small

inductors and results in fast transient response and good

loop stability.

The ultra-low minimum on-time enable constant-frequency

operation even at very high step down ratios. The build-in

spread-spectrum frequency modulation further helping

systems designers with better EMC management.

The RTQ2104 provides complete protection functions such

as input under voltage lockout, output under voltage

protection, over current protection, and thermal shutdown.

Cycle-by-cycle current limit provides protection against

shorted outputs and soft-start eliminates input current

surge during start-up. The RTQ2104 is available in SOP-

8 (Exposed Pad) package.
