Overview
The AP61201Z6-7 is a low-voltage synchronous buck converter manufactured by Diodes Incorporated. It operates with an input voltage range of 2.3 V to 5.5 V and provides an adjustable output voltage from 600 mV to 3.6 V. The device supports a continuous output current of 2 A with a switching frequency of 1.3 MHz. Quiescent current is specified at 19 uA. It is housed in a SOT-563-6 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-side and low-side N-channel MOSFETs for efficient synchronous rectification.
- Includes internal compensation to minimize external component count.
- Features programmable soft-start to limit inrush current during startup.
Applications
- Portable consumer electronics power management
- Battery-powered devices requiring efficient step-down conversion
- Embedded systems with single-supply requirements
Procurement Notes
Verify the specific suffix Z6-7 against the manufacturer datasheet to confirm packaging and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the part number with official Diodes Incorporated documentation to validate availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when an input voltage up to 5.5 V and an output current of 2 A are required. The 1.3 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOT-563 package size constraints and thermal performance relative to the expected load conditions and ambient temperature environment.
Part Context
This part belongs to the AP61201 series of low-voltage synchronous buck converters from Diodes Incorporated. It is designed for applications requiring high efficiency and compact footprint. The series typically shares architectural similarities with other members like the AP61202, differing primarily in output current capabilities or fixed vs. adjustable voltage options.
Replacement Considerations
The AP61202Z6-7 is a documented substitute within the same family, offering similar functionality but potentially different output current ratings. Verify pinout compatibility and electrical parameters against the specific application requirements before substitution.
