Description
LT1937 White LED Step-Up Converter in SC70 and ThinSOT .
Features
* s s s s s s s s s DESCRIPTIO Inherently Matched LED Current High Efficiency: 84% Typical Drives Up to Four LEDs from a 3.2V Supply Drives Up to Six LEDs from a 5V Supply 36V Rugged Bipolar Switch Fast 1.2MHz Switching Frequency Uses Tiny 1mm Tall Inductors Requires Only 0.22µF Output Capacitor LowApplications
* Although small size and high efficiency are major concerns, the inductor should have low core losses at 1.2MHz and low DCR (copper wire resistance). Some inductors in this category with small size are listed in Table␣ 1. The efficiency comparison of different inductors is shown in Figure 4. Table 1LT1937 Distributors
