RTQ2838A 8A, 18V, High-Efficiency Step-Down Converter with Internally-Compensated Fast Current-Mode Control 1 General Description The RTQ2838A is a high-performance, synchronous step-down converter that can deliver up to 8A output current with an input supply voltage range of 4V to 18V. The device integrates low RDS(ON) power MOSFETs, an accurate 0.5V reference and an integrated diode for the bootstrap circuit to offer a very compact solution. The RTQ2838A adopts internally-compensated fast current mode (FCM) control architecture that provides fast transient response and further reduces the external-component count. The FCM operates at a truly fixed switching frequency over the line, load and output voltage range and makes the EMI filter design easier.
