The LTC3528BEDDB-2#TRMPBF is a synchronous, fixed-frequency step-up DC/DC converter from Linear Technology, designed for battery-powered applications. It features a low VIN start-up voltage of 700mV and can operate down to 500mV once started, providing extended run-time.
With a switching frequency of 2MHz, this converter minimizes solution footprint by allowing the use of small inductors and ceramic capacitors. It supports an input voltage range of 0.5V to 5.5V and an output voltage range of 1.6V to 5.25V. The device delivers up to 3.3V at 400mA from two cells or 200mA from a single cell, achieving up to 94% efficiency.
Key features include output disconnect, integrated soft-start, current mode control with internal compensation, and low noise PWM operation. The LTC3528BEDDB-2#TRMPBF also includes anti-ringing circuitry to reduce EMI and a low shutdown current of less than 1µA. It is housed in a compact 2mm x 3mm x 0.75mm DFN package, suitable for space-constrained designs.
Applications include medical instruments, flash-based MP3 players, noise-canceling headphones, wireless mice, and Bluetooth headsets. The device also offers short-circuit protection and thermal overload protection.
