RT5760A/B/C/D 6V 1A, ACOT® Buck Converter in Thin SOT-563 Package General Description Features The RT5760A/B/C/D is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a SOT-563 (FC) package.        The RT5760A/B/C/D adopts Advanced Constant On-Time (ACOT® ) control architecture to provide an   ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT5760A/C operate in automatic PSM that maintain high efficiency during light load operation. The RT5760B/D operate in Forced PWM that help to meet tight voltage regulation accuracy requirements.        The RT5760A/B/C/D senses both FETs current for a robust over-current protection. The device features cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short   Input Voltage Range from 2.5V to 6V Integrated 120m and 80m FETs 1A Output Current, up to 95% Efficiency 100% Duty Cycle for Lowest Dropout 1% Internal Reference Voltage 2.2MHz Typical Switching Frequency Power Saving Mode for Light Loads (RT5760A/C) Low Quiescent Current: 25A (Typ.) Fast Advanced Constant On-Time (ACOT ® ) Control Internal Soft Startup (0.6ms) Enable Control Input Power Good Indicator (RT5760A/B) Both FETs Over-Current Protection Negative Over-Current Protection (RT5760B/D) Input Under-Voltage Lockout Protection Hiccup-Mode Output Under-Voltage Protection Over-Temperature Protection RoHS Compliant and Halogen Free Applications circuit, over current or inductor saturation. A built-in soft-start function prevents inrush current during start-up. The device also includes input under-voltage lockout, output under-voltage protection, and Mobile Phones and Handheld Devices  STB, Cable Modem, and xDSL Platforms  WLAN ASIC Power / Storage (SSD and HDD)  General Purpose for POL LV Buck Converter  over-temperature protection to provide safe and smooth operation in all operating conditions.
