The MAX1533AETJ+T is a dual step-down, switch-mode power supply (SMPS) controller with synchronous rectification, designed for main 5V/3.3V power generation in battery-powered systems. It features fixed-frequency operation with optimal 40/60 interleaving to minimize input ripple current.
Key electrical specifications include an input voltage range of 4.5V to 26V, a typical shutdown current of 5µA, and a reference output of 2V ±0.75%. The device operates within a temperature range of -40°C to +85°C.
This controller is suitable for applications such as 2 to 4 Li+ cell battery-powered devices, notebook and subnotebook computers, PDAs, and mobile communicators. It is available in a 32-pin 5mm x 5mm thin QFN package, suitable for surface mounting.
The MAX1533A/MAX1537A include on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-shutdown. The exposed backside pad on the QFN package improves thermal characteristics.
