Overview
The AP62300Z6-7 is a high-voltage synchronous buck converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.2 V to 18 V and delivers a continuous output current of 3 A. The device provides an adjustable output voltage from 800 mV to 7 V. It features a fixed switching frequency of 750 kHz and a typical quiescent current of 155 uA. The component supports operation within a temperature range of -40°C to +125°C and is housed in a compact SOT-563 package.
Feature Summary
- Integrates high-side and low-side power MOSFETs for efficient step-down conversion
- Utilizes proprietary gate driver design to suppress switching node ringing and reduce EMI noise
- Includes comprehensive protection mechanisms such as overcurrent, thermal, and short-circuit protection
Applications
- Point-of-load regulation in industrial equipment
- Power supply stages for automotive electronics
- Battery-powered devices requiring wide input voltage tolerance
Procurement Notes
Verify the specific suffix and packaging configuration against official Diodes Incorporated documentation before ordering. Confirm that the required operating temperature range and electrical parameters align with the target application specifications. Ensure compliance with relevant environmental standards such as RoHS requirements specified in the manufacturer's datasheet.
Selection Notes
Select this component when a wide input voltage range up to 18 V is required alongside a 3 A output capability. The integrated power switches and fixed frequency operation simplify external component selection. Consider the SOT-563 package size for space-constrained designs requiring high efficiency and robust protection features.
Part Context
This part belongs to the AP6230x series of high-voltage synchronous buck converters from Diodes Incorporated. The series is designed to provide efficient DC-DC conversion with minimal external components. These converters are suitable for applications demanding reliable performance across varying input voltages and load conditions.
Replacement Considerations
AP62301Z6-7 offers similar functionality with potentially different internal compensation or pinout configurations. Verify electrical compatibility and pin-to-pin equivalence before substitution.
