Controls & Controllers

Compact Buck-Boost Regulator delivers up to 300 mA.

Respectively rated to 300 and 275 mA, 3.3 V SC630A and 5 V SC632A come in 2 x 2 x 0.6 mm MLPQ 8-pin package and are designed to be used with 2.2 Â-µF capacitors. Both 3-mode (1x, 1.5x, 2x) charge pumps have 1 MHz fixed frequency, deliver continuous output currents, and operate as LDO linear regulators when input exceeds output. When input is less than required output, devices automatically...

Current Sink LED Backlight Drivers minimize component count.

Intended for high-end handheld displays, SC667 and SC668 can replace boost converters and charge pumps in high-end handhelds while providing display backlighting. Both incorporate smart Automatic Dropout Prevention (ADP) technology, which enables automatic and simultaneous monitoring of each current sink to avoid dropout as system loads turn on and off. While SC668 provides 8 current sinks, SC667...
