Overview
The AP72250CJ12-7 is a synchronous boost DC-DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 600 mV to 5.5 V and provides an adjustable output voltage from 1.7 V to 5.5 V. The device delivers up to 4.7 A of output current at a switching frequency of 900 kHz. Key electrical parameters include a typical quiescent current of 20 uA, high-side power MOSFET resistance of 20 mΩ, and low-side resistance of 26 mΩ. It supports PFM and PWM modes and features a shutdown function. The component is housed in a WLCSP-12 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Synchronous boost topology with integrated high-side and low-side power MOSFETs for efficient step-up conversion.
- Mode programmability allowing selection between Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) operations.
- Ultra-low quiescent current consumption to extend battery life in portable applications.
- Wide input voltage range starting from 600 mV, enabling operation with single-cell lithium-ion batteries or supercapacitors.
Applications
- Battery-powered consumer devices
- USB power supplies
- Power banks
- Supercapacitor charging equipment
- Metering systems
Procurement Notes
Verify the specific suffix CJ12-7 against official Diodes Incorporated documentation to confirm the exact packaging configuration and tape-and-reel specifications. Ensure that the WLCSP-12 package dimensions align with your PCB footprint requirements. Cross-reference the thermal performance data in the datasheet with your system's heat dissipation capabilities to guarantee reliable operation within the specified temperature range.
Selection Notes
Select this component when a compact solution is required for stepping up low input voltages to higher levels. The wide input range makes it suitable for applications using depleted lithium cells or supercapacitors. Consider the 900 kHz switching frequency for balancing component size and efficiency. Verify that the 4.7 A output current capability meets the peak load requirements of the target application circuit.
Part Context
This part belongs to the AP72250 series of mode-programmable synchronous boost converters from Diodes Incorporated. The series is designed for space-constrained environments, utilizing small form-factor packages like WLCSP. It targets modern portable electronics where energy efficiency and minimal board area are critical design constraints.
