Product Overview
LTC3835 is a high performance step-down switching regulator controller that drives an all N-channel synchronous power MOSFET stage. A constant-frequency current mode architecture allows a phase-lockable frequency of upto 650KHz. The 80µA no-load quiescent current extends operating life in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. It features a precision 0.8V reference and a power good output indicator. The TRACK/SS pin ramps the output voltage during start-up. Current foldback limits MOSFET heat dissipation during short-circuit conditions. It is used in applications such as automotive systems, telecom systems, battery-operated digital devices, distributed DC power systems etc.
- OPTI-LOOP® compensation minimizes COUT
- Wide VIN range is 4V to 36V operation
- Dual N-channel MOSFET synchronous drive, very low dropout operation: 99% duty cycle
- Adjustable output voltage soft-start or tracking, output current foldback limiting
- Power good output voltage monitor, clock output for PolyPhase® applications
- Internal LDO powers gate drive from VIN or VOUT
- Burst Mode® operation at light loads
- Shutdown mode is 10µA typical at (VRUN = 0V, TA = 25°C, VIN = 12V, VRUN = 5V)
- Operating temperature is -40°C to 85°C
- Package style is 20-lead plastic TSSOP
