Overview
The ZL2004ALNFT-01 is an adaptive digital DC-DC controller optimized for high output accuracy, serving as a specialized version of the ZL2004 series. It operates with an input voltage range of 8.0V to 10.0V and provides an adjustable output voltage range from 0.9V to 1.1V. The device features ±0.2% VOUT set-point accuracy and supports a switching frequency of 400kHz. Designed for single-output applications, it utilizes a 32-QFN (5x5) package and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Adaptive algorithms enhance efficiency under light load conditions
- Configurable operating features via pinstrap selection, resistor selection, or digital interface
- Supports current sharing for parallel connection of multiple devices
Applications
- High accuracy synchronous buck power conversion systems
- Parallel power supply configurations requiring current sharing
- Digital DC-DC control applications compatible with ZL1505 MOSFET driver ICs
Procurement Notes
Verify the specific suffix '-01' against official Renesas documentation to confirm the exact electrical characteristics and packaging details. Ensure compatibility with the intended ZL1505 MOSFET driver IC. Confirm that the required operating temperature range and input voltage specifications align with the system design requirements before procurement.
Selection Notes
Select this component when high output accuracy is critical, specifically requiring ±0.2% VOUT set-point accuracy. It is suitable for designs needing adaptive light-load efficiency improvements and flexible configuration options. Consider its compatibility with the ZL1505 driver and support for parallel operation if current sharing capabilities are required for the power stage.
Part Context
This part belongs to the ZL2004 family of adaptive digital DC-DC controllers manufactured by Renesas Electronics Corporation. The family is designed to work in conjunction with the ZL1505 MOSFET driver IC. The ZL2004ALNFT-01 variant is specifically optimized for high output accuracy compared to standard versions in the series.
Replacement Considerations
The ZL2004ALNFT-01 is a specialized version of the ZL2004 DC/DC controller. Verify functional equivalence with other ZL2004 variants only if their datasheets explicitly confirm identical high-accuracy specifications and pinout compatibility.
