intersil ISL97634 date data
The ISL97634 is an efficient and highly integrated PWM boost LED driver that is suitable for 1.8” to 3.5” LCDs that employ 2 to 7 white LEDs for backlighting. The ISL97634 features a wide range of PWM dimming control capability. It allows dimming frequency as low as DC to 32kHz beyond audible spectrum. The ISL97634 also features a feedback disconnect switch to prevent the output from being modulated by the PWM dimming signal that minimizes system disturbance. The ISL97634 is available in the 8 Ld TDFN (2mmx3mm) package. There are 14V, 18V, and 26V OVP options that are suitable for 3 LEDS, 4 LEDs, and 7 LEDs (3.5V/20mA type) backlight applications respectively. The ISL97634 is specified for operation over the -40°C to +85°C ambient temperature at input voltage from 2.4V to 5.5V.
intersil ISL97635 date data
ISL97635 is an 8-channel LED driver from Intersil. It supports 8x9 or 8x10 LED strings and can output up to 20mA current. It can be controlled through SMBus, external PWM or analog light sensor.
intersil ISL97635A date data
The ISL97635A is a digitally controlled LED driver that controls 6 channels of LED current for LCD backlight applications. The ISL97635A can drive typically 54 (6x9) pieces of 3.5V/30mA or 60 (6x10) pieces of 3.2V/20mA LEDs. The ISL97635A contains 6 channels of voltage controlled current sources with typical currents matching of ±1%, which compensate for the non-uniformity effect of forward voltages variance in the LED stacks. To minimize the voltage headroom and power loss in the typical multi-strings operation, the ISL97635A features a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output regulation. The LED dimming control can be achieved through a SMBus, an external PWM, or a variable DC (analog light sensor) input. SMBus controlled dimming allows 256 levels each of PWM and DC current adjustments. The SMBus PWM dimming frequency can be adjusted from 100Hz to 5kHz by an external capacitor. External PWM input allows up to 20kHz audio noise free PWM dimming. The SMBus PWM setting and an external PWMI signal can be synchronized for dimming.

intersil ISL6416 handbook
ISL6416 is a triple output low-noise LDO regulator with an integrated microprocessor reset circuit and is optimized for powering wireless chipsets. The IC accepts an input voltage range of 3.0V to 3.6V and provides three regulated output voltages: 1.8V (LDO1), 2.8V (LDO2), and another ultra-clean 2.8V (LDO3). On chip logic provides sequencing between LDO1 and LDO2 for the BBP/MAC and the I/O supply voltage outputs. LDO3 features ultra low noise that does not exceed 30µVRMS (typical) to aid VCO stability. High integration makes the ISL6416 an ideal choice to power many of today’s small form factor industry standard wireless cards such as PCMCIA, mini-PCI and Cardbus-32. The ISL6416 uses an internal PMOS transistor as the pass device. The ISL6416 also integrates a reset function, which eliminates the need for the additional reset IC required in WLAN applications. The IC asserts a RESET signal whenever the VIN supply voltage drops below a preset threshold, keeping it asserted for at least 25ms after Vin has risen above the reset threshold. FAULT indicates the loss of regulation on LDO1.
