RT5710F
1A, 1MHz, 6V CMCOT Synchronous Step-Down Converter
General Description
Features
The RT5710F is a high efficiency synchronous
step-down DC-DC converter. Its input voltage range is
from 2.5V to 6V and provides an adjustable regulated
output voltage from 0.6V to 3.8V while delivering up to
1A of output current.
Efficiency Up to 95%
RDS(ON) 160m HS / 110m LS
VIN Range 2.5V to 6V
VREF 0.6V with 1% Accuracy
CMCOT Control Loop Design for Best Transient
Response, Robust Loop Stability with Low-ESR
(MLCC) COUT
The internal synchronous low on-resistance power
switches increase efficiency and eliminate the need for
an external Schottky diode. The Current Mode
Constant-On-time (CMCOT) operation with internal
compensation allows the transient response to be
optimized over a wide range of loads and output
capacitors.
Fixed Soft-Start 1.2ms
Cycle-by-Cycle Over-Current Protection
Input Under-Voltage Lockout
Output Under-Voltage Protection (UVP Hiccup)
Thermal Shutdown Protection
Power Saving at Light Load
Applications
STB, Cable Modem, & xDSL Platforms
LCD TV Power Supply & Metering Platforms
General Purpose Point of Load (POL)
