Bipolar Darlingtons in a low thermal resistant SOT-89 package

Bipolar Darlingtons  in a low thermal resistant SOT-89 package
Avago Technologies has announced its ADA-4789, a cost-efficient, high linearity silicon bipolar Darlington amplifier in a low thermal resistant SOT-89 package for use up to 2.5GHz. The ADA-4789's unconditional stability and broad bandwidth performance make it ideal for IF amplifier and pre-driver amplifier applications in cellular base stations, as well as IF amplifiers in direct broadcast satellite and cable television infrastructures. Additionally, the internal 50-ohms matching circuitry simplifies design and provides shorter time-to-market.

1.5 Amp LDO from Microchip has many features

1.5 Amp LDO from Microchip has many features
Microchip has announced a 1.5A LDO that incorporates shutdown, power good, programmable power good delay and bond-wire compensation on a single chip. The MCP1727 is a highly efficient, adjustable output, low-power LDO in small, thermally capable packages (8-pin SOIC or 3 mm x 3 mm DFN). The combination of high output current (1.5A) and low output voltage (down to 0.8V) makes the MCP1727 ideally suited for powering a variety of power supply applications including high-performance embedded processors.

600V MOSFETs suit the latest ultra-slim, low-profile ballast applications

600V MOSFETs suit the latest ultra-slim, low-profile ballast applications
Fairchild Semiconductor has developed a family of low on-resistance 600V SuperFET MOSFETs specifically to address the DPAK (TO-252) device requirements of the latest ultra-slim, low-profile ballast applications. To minimize switching and conduction losses and meet system efficiency needs of these fast-switching lighting designs, Fairchild’s DPAK SuperFETs offer as little as one-third the on-resistance (0.6 ~ 1.2 Ohms) of traditional planar MOSFETs. They also have the ability to withstand both high-speed voltage (dv/dt)- and current (di/dt)-switching transients necessary for ballasts to operate reliably at very high frequencies.

Boost converter combines output voltage programming with high output current drive in space-efficient packaging

Boost converter combines output voltage programming with high output current drive in space-efficient packaging
Rated at 24V at 100mA, the AAT1232 is the latest addition to AnalogicTech’s rapidly growing family of boost converters targeted primarily at cost-sensitive OLED, LCD, and CCD applications. The device offers substantial output drive capability in an extremely compact footprint. Operating at a switching frequency up to 2MHz, the AAT1232 reduces PCB footprint by using small-value external inductors and capacitors. For example, the device operates with 2.2µH inductors that are approximately ten times smaller than many competitive boost conductors require. Small TSOP and TDFN packages and fewer external components also help reduce system cost.

Buck controllers are said to deliver industry’s fastest transient response and highest system accuracy

Buck controllers are said to deliver industry’s fastest transient response and highest system accuracy
Intersil has introduced a family of four-phase synchronous pulse width modulation buck controllers that are said to deliver the industry’s highest performance/price ratio for four-phase CPU core regulators. Intel VR10/11 and AMD AM2 CPU core solutions using these advanced controllers meet specs with substantially fewer bulk output capacitors than competitive offerings. The devices provide the industry’s most integrated and cost-efficient computing power management solution.
