The LTC3548EDD from Linear Technology (LT) is a dual, fixed output, constant-frequency, synchronous step-down DC/DC converter. Designed for low power applications, it operates from a 2.5V to 5.5V input voltage range.
This regulator features a constant 2.25MHz switching frequency, enabling the use of small, low-cost inductors and capacitors with a profile of 1mm or less. It achieves high efficiency of up to 95% and boasts very low quiescent current of only 40µA. The device supports output currents of 1.8V at 800mA and 1.575V at 400mA, with high switch currents of 1.2A and 0.7A respectively. It also includes short-circuit protection and 100% duty cycle low dropout operation.
The LTC3548EDD is available in a small, thermally enhanced 3mm x 3mm DFN package, making it suitable for space-constrained designs. Its current mode operation ensures excellent line and load transient response. The ultralow shutdown current further enhances its suitability for battery-powered devices.
