RT6210

500mA, 80V, 350kHz Synchronous Step-Down Converter

General Description

Features

^0.8V Feedback Reference Voltage with 1.5%

The RT6210 is a 80V, 500mA, 350kHz, high-efficiency,

synchronous step-down DC-DC converter with an input-

voltage range of 5.2V to 80V and a programmable output-

voltage range of 0.8V to 72V. It features current-mode

control to simplify external compensation and to optimize

transient response with a wide range of inductors and output

capacitors. High efficiency can be achieved through

integratedN-MOSFETs, and pulse-skipping mode at light

loads. With EN pin, power-up sequence can be more

flexible and shutdown quiescent current can be reduced

to < 3μA.

Accuracy

^Wide Input Voltage Range : 5.2V to 80V

^Output Current : 500mA

^Integrated N-MOSFETs

^Current-Mode Control

^Fixed Switching Frequency : 350kHz

^Programmable Output Voltage : 0.8V to 72V

^Low < 3μA Shutdown Quiescent Current

^Up to 92% Efficiency

^Pulse-Skipping Mode for Light-Load Efficiency

^Programmable Soft-Start Time

 Cycle-by-Cycle Current Limit Protection

 Input Under-Voltage Lockout, Output Under-Voltage

and Thermal Shutdown Protection

The RT6210 features cycle-by-cycle current limit for over-

current protection against short-circuit outputs, and user-

programmable soft-start time to prevent inrush current

during startup. It also includes input under-voltage lockout,

output under-voltage, and thermal shutdown protection to

provide safe and smooth operation in all operating

conditions.

Applications

 4-20mA Loop-Powered Sensors

 OBD-II Port Power Supplies

The RT6210 is available in the SOP-8 (Exposed pad)

package.

 Low-Power Standby or Bias Voltage Supplies

 Industrial Process Control, Metering, and Security

Systems

 High-Voltage LDO Replacement

 Telecommunications Systems

 Commercial Vehicle Power Supplies

 General Purpose Wide Input Voltage Regulation
