Product overview

Description

The STBB3JCC is a fixed frequency, high efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 V to 5.5 V starting from input voltage from 1.8 V to 5.5 V. Thanks to very low sensing voltage, only 100 mV and very low RDS(on) of integrated power MOSFET, it achieves very high efficiency driving high brightness white LED in constant current mode. The device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for cell lithium-Ion applications where the output voltage is within the battery voltage range. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage from either lower power consumption or best dynamic performance. The device also includes soft-start control, thermal shutdown, and current limit. The STBB3JCC is packaged in Flip Chip 20 bumps with 2.5 x 1.75 mm.
  • All features
