DescriptionThe LT1616 is a current mode PWM step-down DC/DC converter with internal 0.6A power switch, packaged in a tiny 6-lead SOT-23. The wide input range of 3.6V to 25V makes the LT1616 suitable for regulating a wide variety of power sources, from 4-cell batteries and 5V logic rails to unregulated wall transformers and lead-acid batteries. Its high operating frequency allow the use of tiny, low cost inductors and ceramic capacitors. With its internal compensation eliminating additional components, a complete 400mA step-down regulator fits onto 0.15 square inches of PC board area.
The constant frequency current mode PWM architecture and stable operation with ceramic capacitors results in lopw, predictable output ripple. Current limiting provides protection against shorted outputs. The low current (<1µA) shutdown provides complete output disconnect, enabling easy power management in battery-powered systems.
