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.
  • Short circuit robust
  • Integrated boost diodes
  • Integrated loop compensation
  • Anti-phase switching reduces ripple
  • <2µA Low shutdown
