RTQ2105-QA

36V_IN, 3A, High Efficiency Synchronous Step-Down

Converter with Low Quiescent Current

General Description

Features

 AEC-Q100 Grade 1 Qualified

 Wide Input Voltage Range

 4V to 36V

The RTQ2105 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.

 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 70mΩ Switch and 70mΩ Synchronous

Rectifier

 Low Quiescent Current : 40μA

 Fast 60ns Minimum Switch On-Time

 Ultra-Short 65ns Minimum Switch Off-Time

 Adjustable and Synchronizable Switching : 300kHz

to 2.2MHz

The wide switching frequency of 300kHz to 2200kHz allows

for efficiency and size optimization when selecting the

output filter components. 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 optional spread-spectrum frequency modulation further

helping systems designers with better EMC management.

 Selectable PSM/FPWM at Light Load

 Optional Spread-Spectrum Frequency Modulation

for Low EMI

 Externally Adjustable Soft-Start

 Power Good Indication

 Enable Control

 Adjustable Output Voltage with Cable Drop

Compensation

The RTQ2105 offers precise constant current and constant

voltage regulation. It is ideally suited for USB power delivery

or charging super-capacitors. For applications that use

long cable, the RTQ2105 offers cable drop compensation

as well to maintain accurate regulation at the end of the

long cable.

 Constant Current (CC) and Constant Voltage (CV)

Regulation

 0.8V 1.5% CV Reference Accuracy

 Adjustable Current Limit

 Adjacent Pin-Short Protection

 Built-In UVLO, UVP, OTP

The RTQ2105 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 RTQ2105 is available in WET-

WQFN-24SL 4x4 (W-Type) package.

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

 USB Power Chargers
