IS31BL3212
manufacturer
ISSI
FOUR CHANNEL CONSTANT CURRENT LED DRIVER
The IS31BL3212 provides four regulated current sources, delivers up to 23mA of load current to accommodate four white LEDs. It requires no charge pump, has no noise and significantly improved the efficiency. The serial digital input is used to enable, disable, and set current for each LED with 16 settings down to 0.69mA. A low-current shutdown feature disconnects the load from the input and reduces quiescent current typically 1.0mA. The IS31BL3212 is available in a Pb-free, space-saving 2mm×2mm DFN-8 package. FEATURES        Ultra low headroom voltage Cost effective LED driver Four channel constant current output ideal for driving LEDs Best noise and efficiency performance Ultra low q...

WHITE LED DRIVER
The IS31BL3228A (IS31BL3228B) is a low noise, constant frequency charge pump DC/DC converter for white LED applications. The IS31BL3228A (IS31BL3228B) is capable of driving up to four (six) channels of LEDs at preset 20mA per channel from a 2.8V to 5.5V input. The current sinks may be operated individually or in parallel for driving higher current LEDs. Only one 1μF small capacitor (at C+ thru C-) and two small 2.2μF capacitors (at VCC and VOUT) are needed, it makes this part ideally suited for small, battery-powered applications. The serial digital input is used to enable, disable, and set current for each LED with 14 settings down to 1.8mA. Each output of the IS31BL3228A/IS31BL322...

ISSI
8-LED BACKLIGHT DRIVER
The IS31BL3229 with a smart charge-pump circuit is a parallel white-LED driver with eight matched 20mA current outputs. It can supply a total output current of 160mA over an input voltage range of 2.7V to 5.5V. IS31BL3229 typically draws less than 1µA when placed in shutdown, and 0.7mA when operating in the no-load and 1X mode condition. If any of the outputs are not used, leave the pin(s) unconnected. Brightness can be controlled by simple-series-control techniques and external PWM signal. IS31BL3229 is available in QFN-20 (3mm × 3mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C. FEATURES              Supply voltage: 2.7V ~ 5.5V 1X, 1.5X operating...

1.5A FLASH/TORCH LED DRIVER
The IS31BL3233A is the ideal power solution for high-power flash LEDs used with cell phone camera modules or digital still cameras. It is a highly integrated step up DC-DC converter with very high switching frequency, fixed at 2MHz, providing a very small total solution for portable photo flash. The IS31BL3233A has separate Flash Mode and Torch Mode enable pins for maximum flexibility. The Flash Mode and Torch Mode LED current is programmed by external resistors respectively, making the flash LED solution simple to control. If both enable pins are at logic high, the LED current will be programmed by the Torch Mode setting resistor. The two LED output sinks can be shorted together externally ...
