Voltage converter IC for cellular phones
BH6040FVM
Description Dimension (Units : mm)
Features
Applications
The BH6040FVM is an IC having the charging-pump
type voltage converter for white LED. Maximum output
current is 80mA and the internal oscillating frequency
is 650kHz. The reduction of power ripple can be realized
due to the built-in regulator on the primary side. Output
(ON/OFF) can be controlled by the external signal and
current consumption at OFF is 1µA (Max).
00W129A
1) Switched capacitor type voltage converter (5.0V output)
2) Easy to solve the noise problems in the VIN side (input side)
3) Built-in SHUTDOWN SW (ON/OFF control)
4) Very small MSOP8 package
