LT1616ES6#TRMPBF

LT1616 is a current mode PWM step-down DC/DC converter with internal 0.6A power switch. The wide input range of 3.6V to 25V makes the device 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 allows 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 low, predictable output ripple. Current limiting provides protection against shorted outputs. It is used in application such as wall transformer regulation, local logic supply conversion: 12V to 5V, 12V or 5V to 3.3V, 2.5V or 1.8V, distributed supply regulation, digital cameras, battery-powered equipment etc.
