Category: Voltage Regulator ICs
LTC3850 is a high performance dual synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 780kHz. Power loss and supply noise are minimized by operating the two controller output stages out of phase. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. Independent TK/SS pins for each controller ramp the output voltages during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The MODE/PLLIN pin selects among Burst Mode® operation, pulse-skipping mode, or continuous inductor current mode and allows the IC to be synchronized to an external clock. Typical applications are notebook and Palmtop computers, portable instruments, battery-operated digital devices, DC power distribution systems.

Features:

  1. Dual, 180° phased controllers reduce required input capacitance and power supply induced noise
  2. High efficiency is up to 95%
  3. RSENSE or DCR current sensing, ±1% 0.8V output voltage accuracy
  4. Phase-lockable fixed frequency 250kHz to 780kHz
  5. Supports pre-biased output, dual N-channel MOSFET synchronous drive
  6. Adjustable soft-start current ramping or tracking, foldback output current limiting
  7. Power good output voltage monitor
  8. Regulated feedback voltage range from 0.792 to 0.808V at ITH1,2 voltage = 1.2V;TA = 25°C
  9. 28-lead (4mm × 4mm) plastic QFN package
  10. Temperature rating range from -40 to 85°C
