The ADP1828YRQZ-R7 is an integrated switching controller for high performance DC-DC converters that is part of a family of high integration solutions for applications such as digital cameras, gaming devices, smartphones and tablets. It is a two-phase synchronous buck controller which is capable of delivering up to 5 A of output current in a compact, thermally efficient package.
The ADP1828YRQZ-R7 features an integrated four-channel digital power system including a general purpose ADC, an integrated FETs driver, configurable protection, a synchronization architecture and an on-board real-time current limit. The ADP1828YRQZ-R7 allows for easy design optimization and offers high-performance power conversion, configurable firmware and exceptional power efficiency.
Application Field
The ADP1828YRQZ-R7 is suitable for a variety of applications such as point of load converters, low power distributed power systems and automotive systems. It is suitable for use in applications that require high accuracy, low-noise operation, low standby power and excellent transient response.
The ADP1828YRQZ-R7 is also well suited for powering SoCs, FPGAs and ASICs requiring a synchronous buck controller operating with low input/output voltages and high performance efficiency. Vehicle DC-DC converters and other industrial applications are also a good fit for the ADP1828YRQZ-R7.
Working Principle
The ADP1828YRQZ-R7 uses a quasi-resonant flyback control architecture with real-time dynamic voltage scaling to maintain accurate voltage regulation. The controller operates in current-mode control and can be configured for either single loop or dual loop operation.
The ADP1828YRQZ-R7 includes cycle-by-cycle current limit, internal overvoltage, undervoltage, overcurrent, thermal shutoff and soft-start protection. It can be configured to shut down when current limit is detected or to operate in constant current mode.
The ADP1828YRQZ-R7 also features programmable current limit and a comprehensive set of fault protection methods, such as positive and negative cycle-by-cycle current limit, overvoltage protection and undervoltage lockout. The integrated inductor current sensing circuit is capable of measuring the inductor current with ±1mV accuracy and can be used for current sharing and other current sensing applications.
The ADP1828YRQZ-R7 is also equipped with a synchronization input and pin that can be used to synchronize the controller’s output with an external clock. The integrated FETs driver provides fast rise and fall times with low switching noise.
The ADP1828YRQZ-R7 is designed for easy integration and high efficiency. It is offered in a VQFN-32 package, allowing for superior power efficiency at a small form factor. Its low operating current and low operating voltage make it ideal for use in low-power applications.
