PMP7892 is an isolated active clamp forward converter capable of 42W output power. This design uses the LM5026 active clamp current-mode controller. Output voltage regulation is maintained using an LMV431 shunt regulator and opto-coupler feedback. Schottky rectifiers allow for holdup of 10ms using the stored charge of the output capacitors. The isolation voltage is 2250 VDC meeting basic insulation requirements.

Normally the output voltage of a switching power supply is higher than the error amplifier reference and so a simple resistive divider between the output voltage and ground at the non-inverting input of the PWM error amplifier is all that is required to set the regulation voltage. However when the output voltage is less than the error amplifier reference voltage the feedback voltage must be div

The PMP5967 reference design provides a 12V/38A output with over 94% efficiency from a 380VDC input. This design uses the UCC25600 to control the resonant LLC converter. The UCC24610 synchronous rectifier controller is used to control two banks of CSD18501Q5A MOSFETs: eliminating the need for heat sinks on the output rectifiers.

The LTC6811 is a multicell battery stack monitor that measures up to 12 series connected battery cells with a total measurement error of less than 1.2mV. The cell measurement range of 0V to 5V makes the LTC6811 suitable for most battery chemistries. All 12 cells can be measured in 290?s, and lower data acquisition rates can be selected for high noise reduction.Multiple LTC6811 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each LTC6811 has an isoSPI interface for high speed, RF-immune, long distance communications. Using the LTC6811-1, multiple devices are connected in a daisy chain with one host processor connection for all devices. Using the LTC6811-2, multiple devices are connected in parallel to the host processor, with each device individually addressed.The LTC6811 can be powered directly from the battery stack or from an isolated supply. The LTC6811 includes passive balancing for each cell, with individual PWM duty cycle control for each cell. Other features include an onboard 5V regulator, five general purpose I/O lines and a sleep mode, where current consumption is reduced to 4?A.Applications Electric and Hybrid Electric Vehicles Backup Battery Systems Grid Energy Storage High Power Portable Equipment

AN115 -- CC112x/CC1175/CC120x Operation in 274-320 MHz Frequency Band

The AD8334 is an ultralow noise, quad channel linear-in-dB variable gain amplifier (VGA). Although optimized for ultrasound systems, it may be used as a low noise variable gain control in any application whose operating frequency is less than 100 MHz.Included in each channel are an ultralow noise preamp (LNA), an X-AMP? VGA with 48 dB of gain range, and a selectable gain postamp with adjustable output limiting. The LNA gain is 19 dB with a single-ended input and differential outputs. Using a single resistor, the LNA input impedance can be adjusted to match a signal source without compromising noise performance.The 48 dB gain range of the VGA makes these devices suitable for a variety of applications. Excellent bandwidth uniformity is maintained across the entire range. The gain control interface provides precise linear-in-dB scaling of 50 dB/V for control voltages between 40 mV and 1 V. Factory trim ensures excellent part-to-part and channel-to-channel gain matching. Differential signal paths result in superb second- and third-order distortion performance and low crosstalk.The AD8334 is a quad version of the single AD8331 and dual AD8332.For information on specs, see the AD8331/AD8332/AD8334 datasheet.Applications Ultrasound and sonar time-gain controls High performance automatic gain control (AGC) systems I/Q signal processing High speed, dual ADC drivers

Today?s high-speed interfaces require strict timings and accurate system design. To achieve the necessary timings for a given system input/output buffer information specification (IBIS) models must be used. These models accurately represent the device drivers under various process conditions. Board characteristics such as impedance loading length number of nodes etc. affect how the device d
