Product Overview
LTC®7800 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage. A constant frequency current mode architecture allows a phase-lockable frequency of up to 2.25MHz. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. This features a precision 0.8V reference and power good output indicator. A wide 4V to 60V input supply range encompasses a wide range of intermediate bus voltages and battery chemistries. The TRACK/SS pin ramps the output voltages during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. The PLLIN/MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous conduction mode at light loads. Typical applications are automotive always-on systems, battery powered digital devices, distributed DC power systems.
- RSENSE or DCR current sensing, selectable current limit, output overvoltage protection
- Selectable continuous, pulse-skipping or low ripple Burst Mode® operation at light load
- Very low dropout operation is 98% duty cycle
- Adjustable output voltage soft-start or tracking, power good output voltage monitor
- Internal LDO powers gate drive from VIN or EXTVCC, no current foldback during start-up
- Feedback current is ±50nA maximum
- Soft-start charge current is 14µA maximum (VTRACK/SS=0V)
- 20-lead plastic QFN package
- Temperature rating range from -40°C to 125°C
