ISL958803+1+1 Voltage Regulator with Expanded ICCMAX Register Range Supporting IMVP8 CFL/CNL CPUs | Power Management (PMIC) | 1 | Active | The ISL95880 is compliant with IMVP8, and provides a complete power solution for Intel microprocessors supporting core, graphics, and system agent rails. The controller provides control and protection for three Voltage Regulator (VR) outputs. The VR A output can be configured for 3-, 2- or 1-phase operation. VR B supports 1-phase operation, and VR C supports 1-phase operation. The address options for these three outputs allow for maximum flexibility to support the IMVP8 CPU. All three VRs share a common serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with a two-chip approach. The ISL95880 has expanded ICCMAXregister tables for VR A and VR C to support Intel CFL-H. Based on the Renesas Robust Ripple Regulator (R3™) technology, the R3 modulator has many advantages compared to traditional modulators. These include faster transient settling time, variable switching frequency in response to load transients, and improved light-load efficiency due to diode emulation mode with load-dependent low switching frequency. The ISL95880 has several other key features. The controller provides PWM outputs, which support Intel DrMOS power stages (or similar) and discrete power stages using the Renesas ISL95808 high voltage synchronous rectified buck MOSFET driver. The controller complies with IMVP8 PS4 power requirements and supports compatible power stages and drivers. The controller supports DCR current sensing with a single NTC thermistor for DCR temperature compensation, or more precision through resistor current sensing. |

ISL97516600kHz/1.2MHz PWM Step-Up Regulator | Evaluation Boards | 4 | Active | The ISL97516 is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With a 2. 0A typical switch current limit and 200mΩ MOSFET, it can deliver over 90% efficiency. The selectable 600kHz and 1. 2MHz allows smaller inductors and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing for the use of low ESR Ceramic output capacitors. When shut down, it draws <1µA of current and can operate down to 2. 3V input supply. These features along with 1. 2MHz switching frequency make it an ideal device for portable equipment and TFT-LCD displays. The ISL97516 is available in an 8 Ld MSOP package with a maximum height of 1. 1mm. The device is specified for operation over the full -40°C to +85°C temperature range. |
| DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 5 | Active | The ISL97519A is a high frequency, high efficiency step-up voltage regulator operated at constant frequency PWM mode. With an internal 2. 0A, 200mΩ MOSFET, it can deliver up to 1A output current at over 90% efficiency. Two selectable frequencies, 600kHz and 1. 2MHz, allow trade offs between smaller components and faster transient response. An external compensation pin gives the user greater flexibility in setting frequency compensation allowing the use of low ESR Ceramic output capacitors. When shut down, it draws <1µA of current and can operate down to 2. 3V input supply. These features, along with 1. 2MHz switching frequency, make it an ideal device for portable equipment and TFT-LCD displays.

ISL97634White LED Driver with PWM Dimming | Power Management (PMIC) | 2 | Active | The ISL97634 represents an efficient and highly integrated PWM boost LED driver that is suitable for LED backlighting in small size LCD panels. With integrated Schottky diode, OVP, and wide range of PWM dimming capability, the ISL97634 provides a simple, reliable, and flexible solution to the backlight designers. 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 various number of LEDs in series. The ISL97634 is specified for operation over the -40°C to +85°C ambient temperature at input voltage from 2. 4V to 5. 5V. |
