RTQ2833A
Description
The RTQ2833A is a high-performance, synchronous step-down converter that can deliver up to 3A 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 pact solution.
The RTQ2833A adopts internally-pensated fast current-mode (FCM) control architecture that provides fast transient response and further reduces the external-ponent 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.
The device offers a variety of functions for more design flexibility. The selectable switching frequency allows the RTQ2833A to meet various application requirements. An independent enable control input pin and a power-good indicator are provided for easy sequence control. The built-in spread-spectrum frequency modulation further helps system designers with...
