Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.3V LDOs

The RT6575C/D is a dual-channel step-down controller generating supply voltages for battery-powered systems. It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and two fixed 5V/3.3V linear regulators. Each linear regulator provides up to 100mA output current and 3.3V linear regulator provides 1% accuracy under 35mA. The RT6575C/D has an oscillator output to drive the external charge pump application. Other features include on-board power-up sequencing, a powergood output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown. A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient. For maximizing power efficiency, the RT6575C/D automatically switches to the diode-emulation mode in light load applications. To eliminate noise in audio applications, an audio-skipping mode is included, which maintains the switching frequency above 25kHz. The RT6575C/D is available in the WQFN-20L 3x3 package.

Please make sure you have advanced soldering skill to solder the chips that you will order from us. When you receive before using it, please confirm the chip you received is brand new as described,if you suspect the chip is not new or not as described. Please don't use it and contact us immediately. Once it has been used, no return will be accepted. Please check before you buy it.Thanks for your understanding.

Lead solder balls' melting point is 180?, 210?-215? is the best melting temperature.
Lead Free solder balls' melting point is 217?, 235?-245? is the best melting temperature.

The temperatures listed above are the chip's solder balls actual temperatures (they are measured by the measuring wire on theBGA machine),but not the temperatures from the BGA rework station's top bottom heat guns.

If soldering a new Lead solder balls chip with Lead Free temperature curve (profile), it will overheat the new chip.
If soldering a new Lead Free solder balls chip with Lead temperature curve (profile), it will not completely melt the lead free solder balls on the new chip.

Most of the laser head have one or twoanti-static pointto prevent static burn laser tube as a security measure. It's better to wear an antistatic wrist strap or wash your hands before welding and installation.

When using a high-grade anti-static soldering iron,you can remove the anti-static point directly, ordinary iron requires special attention, heat iron to reached soldering temperature,then remember to turn off the iron's power, prevent static of iron burn laser tube
