LM2734XQ/LM2734YQ are AEC-Q100 Grade 1 qualified and are manufactured on an Automotive Grade Flow
Description
The LM2734 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 6-pin Thin SOT23 package. It provides
all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest
possible PCB area.
With a minimum of external components and online design support through WEBENCH®
™, the LM2734 is easy to use. The ability to drive 1A loads with an internal 300mΩ NMOS switch using state-of-the-art 0.5µm
BiCMOS technology results in the best power density available. The world class control circuitry allows for on-times as low
as 13ns, thus supporting exceptionally high frequency conversion over the entire 3V to 20V input operating range down to
the minimum output voltage of 0.8V. Switching frequency is internally set to 550kHz (LM2734Y) or 1.6MHz (LM2734X), allowing
the use of extremely small surface mount inductors and chip capacitors. Even though the operating frequencies are very high,
efficiencies up to 90% are easy to achieve. External shutdown is included, featuring an ultra-low stand-by current of 30nA.
The LM2734 utilizes current-mode control and internal compensation to provide high-performance regulation over a wide range
of operating conditions. Additional features include internal soft-start circuitry to reduce inrush current, pulse-by-pulse
current limit, thermal shutdown, and output over-voltage protection.
The SP16160CH1RB demonstrates a high-IF sampling receiver subsystem that provides signal amplification, digitization and clocking as used in wireless infrastructure systems. The subsystem includes the ADC16DV160 analog-to-digital converter (ADC), LMH6517 Digitally-controlled Variable-Gain Amplifier (DVGA) and LMK04031B precision clock conditioner.
Contains most recent Beta version of WaveVision 5 software (v5.0.5.175) and patch to support SP16160CH1RB
This kit requires the Wavevsn Brd 5.1 which must be purchased separately

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
