    LT3988HMSE#PBF Product overview

    Adjust the voltage level of your devices with this step down LT3988HMSE#PBF DC to DC converter from Linear Technology. This converter"s single output can produce a current up to 1 A. Use this part at voltages between 4.1 V and 60 V. With an adjustable output that has a voltage of 0.75 to 59.4 V, this is power management at its best. Using a line regulation of 0.01%/V(Typ) is needed for a programmable DC power supply. It has a switching frequency of 250 to 2500 kHz. This converter has an operating temperature range of -40 °C to 150 °C.

    LT3988IMSE#PBF Product overview

    The LT3988IMSE#PBF is a dual current mode step-down DC/DC Converter that accepts two input voltages up to 60V (80V transient), which may be driven from separate supplies or can be cascaded. High efficiency switches are included on the die along with internal boost diodes and loop compensation. Both converters are capable of generating 1A outputs, are synchronized to a single oscillator programmable up to 2.5MHz and run with opposite phases, reducing input ripple current. The switching frequency is set with a single resistor yielding a range of 250kHz to 2.5MHz or a clock signal can be applied to the SYNC pin. The LT3988"s high switching frequency allows the use of small inductors and capacitors, resulting in a very small dual output supply. The constant switching frequency, combined with low impedance ceramic capacitors, results in low, predictable output ripple. A current mode PWM architecture provides fast transient response with cycle-by-cycle current limiting.
