DC-DC converters are devices capable of converting one DC voltage to a different value, either higher or lower. The output is isolated from the input.  PT6506A DC-DC converter is in the buck-boost configurable converter family. It is a current-mode synchronous step-down DC-DC converter with integrated power FETs for load applications. The device employs a constant on-time control, and is capable of robust transient load performance at high conversion ratios. The PT6506A is available in a space-saving WLCSP-14 package.

Application Field

The PT6506A DC-DC converter has wide applications, such as IoT, wearables, battery powered systems, and sensor interface. It can be used in applications that require both high-accuracy, low-dropout voltage regulation and very low quiescent current when tracking the input voltage. Its buck-boost configurability means that it can automatically move between step-down and step-up operation depending on load current, allowing it to handle both positive and negative battery voltage. This makes it suitable for battery-powered designs, such as health monitors, watches, other IoT designs, as well as in automotive applications.

Working Principle

The PT6506A DC-DC buck-boost converter combines synchronous rectification and forced continuous current mode with integrated power FETs. The converter is capable of responding to rapid load changes, with no latch-up, while meeting the desired step-down and step up operation. This is achieved by the device’s adaptive regulation loop which dynamically adjusts the required on time of a given output voltage.

The PT6506A also includes a number of built-in safeguards which make it suitable for applications without complex additional circuitry to manage current, voltage, and power. Pulse-by-pulse current limit, thermal shutdown, and a voltage-limited soft start are all included on the device. These features provide robust and simple protection for the application, with no additional components required.

The output voltage can be set using an external resistor divider resulting in less than 1% temperature coefficient over the operating range. Additionally, the external divider can be trimmed to set the output voltage to a specific voltage.

The PT6506A step-down/step-up DC-DC converter is capable of operating at high efficiencies over a wide input and output voltage range. It also offers a high levels of performance and integration. It is suitable for use in a wide range of applications, from wearable health systems to automotive designs.
