TB62752AFUG
Step Up Type DC/DC Converter for White LED
Features
The TB62752AFUG is a high efficient Step-Up Type DC/DC
Converter specially designed for constant current driving of White
LED.
This IC can drive 2-8 white LEDs connected series using a Li-ion
battery.
This IC contains N-ch MOS-FET Transistor for Coil-Switching, and
LED Current (IF) is set with an external resistor.
This IC is especially for driving back light white LEDs in LCD of PDA,
Cellular Phone, or Handy Terminal Equipment.
Characteristics
• 2-8 white LEDs connected series (Typ. 7LEDs)
• Variable LED Current IF is set with a external resistor :
20 mA (Typ.) @RSENS = 15 Ω
• Output Power : Available for 800mW LED loading
• High Efficiency : 80% over (Using recommended external parts: Typ. 7LEDs)
• Output Over Voltage Shutdown Function :
Switching Operation is shut downed when OVD terminal Voltage is over 37 V (typ.).
• IC Package : SSOP6=p=0.95B
• Switching Frequency : 1.1 MHz (Typ.)
Pin Assignment (Top view)
Caution 1:
This IC could be destroyed in some case if amounted in 180° inverse direction.
Please be careful about IC direction in mounting.
Weight: 0.016 g (Typ.)
