Linear Technology announcesd the H-grade version of the a small footprint 550kHz fixed frequency step-up DC/DC controller that is specified over a -40°C to150°C junction temperature range.

Linear Technology introduced the LTC3867, a fixed frequency synchronous step-down DC/DC controller with nonlinear control, differential output voltage sensing and clock synchronization. Nonlinear control minimizes the output voltage excursion during load transient events by increasing the operating frequency, allowing the LTC3867 to recover from a large load step in only a few cycles. This feature reduces the maximum deviation from nominal by up ...

Linear Technology just announced the LTC3787, high power two phase single output synchronous step-up DC/DC controller, which replaces the boost diodes with high efficiency N-channel MOSFETs. This solution eliminates the heat sink normally required in medium to high power boost converters. The LTC3787 can produce a 24V at 10A output from a 12V input at up to 97% efficiency. The LTC3787's 135uA standby quiescent current when configured for Burst M...

Linear Technology announces the LT3759, a wide input range DC/DC controller for boost, SEPIC and inverting power supply applications, capable of generating either positive or negative regulated output voltages. The LT3759 has two voltage feedback error amplifiers and reference voltages. One set is for positive output voltages, the other is for negative output voltages, both off a single feedback pin, making the LT3759 a highly versatile DC/DC con...

Linear Technology announces the LTC3115-1, a synchronous buck-boost converter that delivers up to 2A of continuous output current from a wide range of power sources from single-cell Li-Ion to 24V/28V industrial rails to 40V automotive inputs. The LTC3115-1’s 2.7V to 40V input and output range provides a regulated output with inputs above, below or equal to the regulated output.

Universal Voltronics’ line of BRC switching power supplies are notable for low ripple, fast transient response, endurance to repetitive arcing and stable output even in the face of line voltage and load charges. Power is converted using advanced IGBT’s switching at frequencies above 20kHz, and controlled using tuned pulse width modulation techniques.
