The LT3506IDHD#PBF is a dual monolithic step-down switching regulator from Analog Devices, designed for efficient power conversion. Each of the two integrated regulators can deliver up to 1.6A of output current.
This device operates with a wide input voltage range of 3.6V to 25V, making it suitable for various power sources including batteries and unregulated wall transformers. The switching frequency is 575kHz, allowing for the use of small external components like inductors and capacitors, which contributes to a compact solution size. The regulators are synchronized to a single oscillator and operate in anti-phase to reduce input ripple current.
Key features include independent shutdown and soft-start circuits for each regulator, as well as independent power-good indicators that simplify power supply sequencing. The current mode PWM architecture ensures fast transient response and cycle-by-cycle current limiting for protection. Frequency foldback and thermal shutdown further enhance its robustness.
The LT3506IDHD#PBF is available in a 16-lead thermally enhanced 5mm x 4mm DFN surface mount package, designed for efficient heat dissipation.
