isl6414 is an ultra-low noise triple output LDO regulator with 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), 2.84V (LDO2), and another ultra clean 2.84V (LDO3). On-chip logic provides sequencing between LDO1 and LDO2 for BBP/MAC and I/O supply voltage outputs. LDO3 features ultra low noise that does not typically exceed 30µV RMS to aid VCO stability. High integration and the thin Quad Flat No-lead (QFN) package makes ISL6414 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 ISL6414 uses an internal PMOS transistor as the pass device. The SHDN pin controls LDO1 and LDO2 outputs whereas SHDN3 controls LDO3 output. Internal voltage sequencing insures that LDO1 output (1.8V supply) is always stabilized before LDO2 is turned on. When powering down, power to the LDO2 is removed before the LDO1 output goes off. The ISL6414 also integrates RESET function, which eliminates the need for 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. An output fault detection circuit indicates loss of output voltage.

ISL6119 is a USB dual port power controller from Intersil that provides fully independent overcurrent (OC) fault protection. This device operates over the +2.5V to +5.5V range and features internal current monitoring, accurate current limiting, integrated power switches and current limited delay to latch-off for system protection. The ISL6119 current sense and limiting circuitry sets the current limit to a nominal 1A, making this device well suited for the USB port power management application. The ISL6119 provides OC fault notification, accurate current limiting and a consistent timed latch-off thus isolating and protecting the voltage bus in the presence of an OC event or short circuit. The 12ms time to latch-off is independent of the adjoining switch’s electrical or thermal condition and the OC response time is inversely related to the OC magnitude. Each ISL6119 incorporates in a single 8 lead SOIC package two 80mΩ N-channel MOSFET power switches for power control. Each switch is driven by a constant current source giving a controlled ramp up of the output voltage. This provides a soft start function to prevent current overshoot.

The HMP8170 NTSC and PAL encoder is a high-quality video encoder that supports YCbCr digital video data driving P0-P15 inputs, optionally lowpass filtered to 6MHz and driving the Y analog output. Cb and Cr are each lowpass filtered to 1.3MHz, quadrature modulated, and added together. The result drives the C analog output. The digital Y and C data are also added together and drive the two composite analog outputs. The DACs can drive doubly-terminated (37.5Ω) lines, and run at a 2x oversampling rate to simplify the analog output filter requirements.
