Product Overview
LTC7804 is a high performance synchronous boost DC/DC switching regulator controller that drives an all N-channel power MOSFET stage. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements. A constant frequency current mode architecture allows a phase-lockable switching frequency of upto 3MHz. It operates from a wide 4.5V to 40V input supply range. When biased from the boost converter output, it can operate from an input supply as low as 1V after startup. The very low no-load quiescent current extends operating runtime in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous inductor current mode at light loads. It is used in application such as automotive and transportation, industrial, military/avionics, telecommunications etc.
- Synchronous operation for highest efficiency and reduced heat dissipation
- Spread spectrum operation
- Pass-Thru™/100% duty cycle capability for synchronous MOSFET
- RSENSE or inductor DCR current sensing
- Selectable continuous, pulse-skipping, or Low Ripple Burst Mode® operation at light loads
- Low operating current is 14μA typ at (VSENSE+
2.9V, EXTVCC = 0V) - Shutdown current is 1.2μA typical at (RUN = 0V, TA = 25°C)
- Programmable frequency is 100KHz typ at (RFREQ = 374Kohm, PLLIN/SPREAD = 0V)
- Operating temperature is -40°C to 125°C
- Package style is 16-lead plastic QFN
