High Efficiency Synchronous Step-Down Converter

® RTQ2822A/B 12A, 17V, High Efficiency Synchronous Step-Down Converter General Description The RTQ2822A/B is a high-performance, synchronous step-down converter that can deliver up to 12A output current with an input supply voltage range of 4.5V to 17V. The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode for bootstrap circuit to offer a very compact solution. The RTQ2822A/B adopts Advanced Constant On-Time (ACOT®) control architecture that provides ultrafast transient response and further reduce the externalcomponent count. In steady states, the ACOT®operates in nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier. The device offers a variety of functions for more design flexibility. The selectable switching frequency, current limit level and PWM operation modes makes the RTQ2822A/B easy-to-use over wide application range. Independent enable control input pin and power good indicator are also provided for easy sequence control. To control the inrush current during the startup, the device provides a programmable soft start-up by an external capacitor connected to the SS pin. Fully protection features are also integrated in the device including the cycle-by-cycle current limit, OVP, UVP, input UVLO and OTP. The RTQ2822A/B is available in a thermally enhanced VQFN-18L 3.5x3.5 (FC) package. Features  4.5V to 17V Input Voltage Range  Integrated 9.8mΩ/4.5mΩ MOSFETs  0.
