buck boost L2596

High‑Performance Synch Buck‑Boost L2596 – 1‑A RMS, 1‑MHz Switching

The L2596 is a dual‑synchronous step‑up/step‑down converter that delivers a highly efficient, low‑noise output from a wide range of input voltages. It integrates the switching MOSFETs and gate drivers into a single compact package, offering 1.5 A of sustainable output current and a generous 90–95 % efficiency at full load. The 1 MHz switching frequency minimizes output ripple and allows for smaller passive components, making it ideal for compact, high‑density power modules.

Typical applications include powering mixed‑signal ICs from battery sources, providing regulated 3.3 V or 5 V rails in power‑constrained IoT devices, and up‑stepping battery voltages to voltage‑sensitive peripherals.

• Input Voltage Range: 2.3 V – 12 V (mid‑rated)
• Output Voltage Range: 0.7 V – 20 V (programmable via external resistors)
• Peak Current: 1.5 A (continuous)
• Common Use Case: Battery‑powered microcontroller systems that require a stable 3.3 V supply from 5‑V to 12‑V inputs
