Overview
The ADP5133ACBZ-R7 is a dual-output, adjustable step-down switching regulator manufactured by Analog Devices Inc. It features two independent buck converters, each capable of delivering up to 800 mA of output current. The device operates with an input voltage range of 2.3 V to 5.5 V and provides adjustable output voltages from 0.8 V to 3.8 V per channel. It supports a high switching frequency of 3 MHz, enabling the use of smaller external passive components. The component is housed in a 16-ball Wafer-Level Chip Scale Package (WLCSP) and is rated for operation over an extended temperature range of -40°C to +125°C.
Feature Summary
- Dual independent buck converter channels providing flexible power distribution
- High-frequency 3 MHz switching operation for compact passive component sizing
- Integrated shutdown control for efficient power management
- Compact WLCSP package suitable for space-constrained designs
Applications
- Portable electronic devices requiring multiple low-voltage rails
- Battery-powered systems needing efficient DC-DC conversion
- Embedded applications with strict size limitations
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the ACBZ designation matches the required temperature grade and package variant. Ensure compatibility with the target PCB footprint for the 16-ball WLCSP. Cross-reference the datasheet revision to confirm electrical characteristics align with design requirements.
Selection Notes
Select this component when dual isolated or non-isolated buck outputs are required within a minimal footprint. The 3 MHz frequency allows for significant reduction in inductor and capacitor sizes compared to lower-frequency alternatives. Verify that the total load current does not exceed the combined capability of both channels while maintaining thermal performance within the specified operating temperature range.
Part Context
This part belongs to the ADP5133 family of dual buck regulators from Analog Devices. It is designed for applications requiring high efficiency and small solution size. The CBZ suffix denotes the specific WLCSP package type used in this variant.
Replacement Considerations
Check for ADP5133 variants with different suffixes if alternative packaging or temperature grades are needed. Verify pinout compatibility before substituting with other dual buck regulators from different manufacturers.
