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 (I
F
) 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 I
F
is set with a external resistor :
20 mA (Typ.) @RSENS = 15
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
