TB62756FUG
Step-up Type DC/DC Converter for White LEDs
The TB62756FUG is a high efficiency step-up type DC/DC
converter that is designed especially for use as a constant current
driver of white LEDs.
It is possible to drive 2 - 6 white LEDs connected in series using a
lithium-ion battery.
This IC incorporates an N-ch-MOS transistor requiredfor
switching of an external inductor.
The forward current of the LEDs can be controlled by an external
resistor. A pulse input system (PWM) can be used as a brightness
control function.
This IC is best suited for use as a driver of white LED back
lighting in color LCDs in PDAs, cellular phones and handy
terminal devices.
This device is Pb-free product.
Features
• Can drive 2-6 white LEDs connected series
• Variable LED Current IF is set with a external resistor :
20 mA (Typ.) @RSENS = 16 Ω
• Output Power : Available for 400mW LED loading
• High Efficiency : 87% @Maximum (Using recommended external parts: Typ. 4LEDs)
• IC Package : SSOP6-P-0.95 (SOT23-6)
• Switching Frequency : 1.1 MHz (Typ.)
Weight: 0.016 g (typ.)
