BD9486F is a high efficiency driver for white LEDs and is designed for large LCDs. BD9486F has a Boost DCDC converter that employs an array of LEDs as the light source.
BD9486F has some protect functions against fault conditions, such as over-voltage protection (OVP), over current limit protection of DCDC (OCP), LED OCP protection, and Over Boost protection (FBMAX). Therefore it is available for the fail-safe design over a wide range output voltage.
■ DCDC converter with current mode
■ VOUT discharge function at shutdown
■ LED protection circuit (Over Boost protection, LED OCP protection)
■ Over-voltage protection (OVP) for the output voltage Vout
■ Adjustable soft start
■ Adjustable oscillation frequency of DCDC
■ Wide range of analog dimming 0.2V to 3.0V
■ UVLO detection for the input voltage of the power stage
General Description The TS1935 Switching regulator is current –mode Boost converters operating at fixed frequency of 1.6MHz. The use of SOT-25 made possible by the minimal power loss of the internal 1.6A switch, and use of small inductor and capacitors result in the industry’s highest power density. The 30V internal switch makes these solutions perfect for Boosting to voltages up to 30V. These parts have a logic-level shutdown pin that can be used to reduce quiescent current and extend battery life. Protection is provided through cycle-by-cycle current limiting and thermal shutdown. Internal compensation simplifies and reduces component count.
