RTQ2106-QA

36V_IN, 3A, High Efficiency, 2.1MHz, Synchronous Step-

Down Converter with Low Quiescent Current

General Description

Features

 AEC-Q100 Grade 1 Qualified

The RTQ2106 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 V_IN. The low quiescent current design with the integrated

low R_DS(ON)power MOSFETs achieves high efficiency over

the wide load range. The peak current mode control with

simple external compensation allows the use of small

inductors and results in fast transient response and good

loop stability.

 Wide Input Voltage Range

 4V to 36V

 3V to 36V (Soft-start is finished)

 Wide Output Voltage Range : 0.8V to V_IN

 Maximum Output Current : 3A

 Peak Current Mode Control

 Integrated 90mΩ Switch and 90mΩ Synchronous

Rectifier

 Low Quiescent Current : 40μA

 Fast 60ns Minimum Switch On-Time

 Ultra-Short 65ns Minimum Switch Off-Time

 Synchronizable Switching : 300kHz to 2.2MHz

 Selectable PSM/FPWM at Light Load

 Built-In Spread-Spectrum Frequency Modulation for

Low EMI

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

operation even at very high step down ratios. For switching

noise sensitive applications, it can be externally

synchronized from 300kHz to 2200kHz. The build-in

spread-spectrum frequency modulation further helping

systems designers with better EMC management.

 Externally Adjustable Soft-Start

 Power Good Indication

 Enable Control

The RTQ2106 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 RTQ2106 is available in

TSSOP-14 (Exposed Pad) package.

 0.8V 1.5% Reference Accuracy

 Adjustable Current Limit

 Adjacent Pin-Short Protection

 Built-In UVLO, UVP, OTP

Applications

 Automotive Systems

 Car Camera Module and Car Cockpit Systems

 Connected Car Systems

 Point of Load Regulator in Distributed Power Systems

 Digital Set Top Boxes

 Broadband Communications
