The LM3354 is a CMOS switched capacitor DC/DC converter that produces a regulated output voltage by automatically stepping up (boost) or stepping down (buck) the input voltage. It accepts an input voltage between 2.5V and 5.5V. The LM3354 is also available with standard output voltages of 1.8V, 3.3V, 3.7V, 4.1V (ideal for white LED applications), and 5.0V. If other output voltage options between 1.8V and 5.0V are desired, please contact your National Semiconductor representative. The LM3354's proprietary buck-boost architecture enables up to 90mA of load current at an average efficiency greater than 75%. Typical operating current is only 375 A and the typical shutdown current is only 2.3 A. The LM3354 is available in a 10-pin MSOP package. This package has a maximum height of only 1.1 mm. |
