General Description

Switch terminal for DC/DC converter.

Nch MOSFET built-In.

Over voltage protection terminal.

Overview

TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB62763FMG Step Up Type DC/DC Converter for White LED TB62763FMG The TB62763FMG is a high efficient Step-Up Type DC/DC Converter specially designed for constant current driving of White LED.

This IC can drive 2-6 Hi-current type 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.

Key Features

  • Variable LED current IF is set with a external resistor: 80mA (typ. ).
  • High current accuracy: +/- 1.5%.
  • High output power : 3W LED loading @(VOUT=20V, VIN=5V).
  • High efficiency: 80% over (using recommended external parts and recommended circuit condition).
  • Output over voltage shutdown function : Switching operation is shut downed when OVP terminal voltage is over 32.5 V (typ. ).
  • Soft start function included.
  • Adjustable switching frequ.
