TPS40021

Enhanced low input (2.25V-5.5V), up to 1MHz synchronous buck controller with output drive/sink current

illustrate

 

The DC-DC controller TPS4002x series is designed for nonisolated synchronous buck regulators that provide operational and design flexibility through user-programmable enhancements.

The TPS4002x uses a proprietary predictive gate drive ™ technique to minimize losses associated with diode turn-on transitions to high-side and synchronous rectifier N-channel MOSFETs. An integrated charge-pump boost circuit provides regulated 5 - V gate drive for two high-side and synchronous rectified N-channel MOSFETs. The combination of predictive gate lane ™ technology and charge pump usage/boost circuitry provides efficient, smaller, and less expensive converters.

Design flexibility is provided by user programmable functions such as operating frequency, short-circuit current detection threshold, soft-start ramp time, frequency, and external synchronization.

 

characteristic

 

  • The operating input voltage is 2.25 V to 5.5 V
  • The output voltage is 0.7V low
  • 1% with an internal 0.7 V reference
  • Predicting gate drive ™N-channel MOSFET drivers is more efficient
  • Externally adjustable soft-start and short-circuit current limit
  • Programmable fixed-frequency 100 kHz to 1 MHz voltage mode control
  • The source is only current or source/sink current
  • Fast transient response output comparators provide a power good output status indication and
