With a minimum of external components • High Switching Frequency the LM3410 is easy to use. It can drive 2.8A typical peak currents with an internal 170 m Ω NMOS switch. – 525 KHz (LM3410Y) Switching frequency is internally set to either 525 kHz – 1.6 MHz (LM3410X) or 1.60 MHz, allowing the use of extremely small • 170 m Ω NMOS Switch surface mount inductors and chip capacitors. Even though the operating frequency is high, efficiencies • 190 mV Internal Voltage Reference up to 88% are easy to achieve. External shutdown is • Internal Soft-Start included, featuring an ultra-low standby current of 80 • Current-Mode, PWM Operation nA. The LM3410 utilizes current-mode control and internal compensation to provide high-performance • Thermal Shutdown over a wide range of operating conditions. Additional • LM3410Q is AEC-Q100 Grade 1 Qualified and features include dimming, cycle-by-cycle current limit, is Manufactured on an Automotive Grade Flow and thermal shutdown. APPLICATIONS • LED Backlight Current Source • LiIon Backlight OLED and HB LED Driver • Handheld Devices • LED Flash Driver • Automotive Typical Boost Application Circuit 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPad is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
