Description
GM1937 WHITE LED STEP-UP CONVERTER .
Features
* High Efficiency: 84% Typical 36V internal Switch Fast 1.2MHz Switching Frequency Drives Up to three LEDs from a 2.8V Supply Drives Up to six LEDs from a 5V Supply External Matched LED Current Uses Tiny 1mm height inductor Requires Only 0.22 ¡@ F Output Capacitor Low profile TSOT paApplications
* 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. Table 1. Recommended Inductors Part Number LQH3C220 ELJTC220KF CDRH3D16-220 LB2GM1937 Distributors
