6-rows 30 mA LEDs driver
The PM6600 consists of a high efficiency monolithic boost converter and six controlled current generators (ROWs), specifically designed to supply LEDs arrays used in the backlight of LCD panels. The device can manage a nominal output voltage up to 36 V (i.e. 10 White-LEDs per ROW). The generators can be externally programmed to sink up to 30 mA and they can be dimmed via a PWM signal (1% dimming dutycycle at 20 kHz can be managed). The device allows to detect and manage the open and shorted LED faults and to let unused ROWs floating. Basic protections (Output Over-Voltage, internal MOSFET Over-Current and Thermal Shutdown) are provided. Backlight driver section – Six rows with 30 mA maximum...

The PM6602 consists of a high-efficiency monolithic boost converter and eight controlled current generators (ROWs), specifically designed to supply LED arrays used in the backlights of LCD panels. The device can manage a nominal output voltage of up to 36 V. The generators can be externally programmed to sink up to 30 mA and they can be dimmed in two different modes: via a PWM signal (1% dimming duty-cycle at 20 kHz can be managed) or in SMBus mode. The device can detect and manage the open and shorted LED faults. The device detects the unused ROWs (connected to SGND). Basic protections (output overvoltage, internal MOSFET overcurrent and thermal shutdown) are provided. ■ Applications ■ ■ ...

Single-phase Switching DC-DC Controllers & Smart Regulators
The PM6652 is a single phase, step-down SMPS controller with high precision 7 bit DAC. It has been designed to supply the CPU and the graphics core (render engine) of the Intel® mobile platform, according with Intel MVP6.5 specifications. The PM6652 can also be configured to supply the 7-bit family, VR11 compliant, ATOM® processors. The controller, based on constant on-time (COT) architecture, allows real-time dynamic switching of the core operating voltages and frequencies, working in both performance and suspend render states. An embedded integrator control loop compensates the DC voltage error due to the output ripple. The high efficiency at light load, achieved with pulse skipping workin...

High Efficiency Step Down Controller
The PM6675A device consists of a single high efficiency step-down controller and an independent Low Drop-Out (LDO) linear regulator. The Constant On-Time (COT) architecture assures fast transient response supporting both electrolytic and ceramic output capacitors. An embedded integrator control loop compensates the DC voltage error due to the output ripple. Selectable low-consumption mode allows the highest efficiency over a wide range of load conditions. The low-noise mode sets the minimum switching frequency to 33kHz for audio-sensitive applications. The LDO linear regulator can sink and source up to 2Apk. Two fixed current limit (±1A- ±2A) can be chosen. An active Soft-End is independentl...
