LTC7878規(guī)格書詳情

DESCRIPTION

The LTC?7878 is a high performance buck-boost switching

regulator controller that operates from an input voltage

above, below or equal to the output voltage. The constant-

frequency, peak current mode architecture allows

a phase-lockable switching frequency of up to 600kHz,

while a programmable input or output current loop regulates

the average input or output current accurately supporting

battery charging applications. With a wide 5V to

70V input and output range and seamless, low noise transitions

between operating regions, the LTC7878 is ideal

for industrial and telecom systems.

The LTC7878 features forced continuous mode (FCM)/

pulse-skipping mode operation. It supports multiphase/

multi-ICs parallel operation for high power applications.

Additional features include 7V N-Channel gate drivers,

smart EXTVCC auxiliary supply and programmable inductor

peak current limit. A PGOOD pin indicates when the

output is within 10 of its designed set point.

The LTC7878 is available in a low profile 32-Lead QFN package.

FEATURES

- Single Inductor Architecture Allows VIN Above, Below or Equal to the Regulated VOUT

- Synchronous Rectification: Up to 98 Efficiency

- Wide VIN Voltage Range: 5V to 70V

- ±1 Output Voltage Accuracy: 1V ≤ VOUT ≤ 70V

- DCR or RSENSE Current Sensing

- Peak Current Mode Control in Buck/Boost/Buck-Boost Mode

- Programmable Input or Output Current Regulation

- 7V NMOS Gate Drivers

- Phase-Lockable Frequency (100kHz to 600kHz)

- Multiphase/Multi-ICs Parallel Operation

- Selectable Continuous or Pulse-Skipping Mode Operation and Inductor Peak Current Limits

- Small 32-Lead 5mm × 5mm QFN Package

APPLICATIONS

- Industrial and Telecom Systems

- Distributed DC Power or Battery Systems
