STBB2 800 mA 2.5 MHz, high efficiency dual mode buck-boost DC-DC converter Datasheet - production data * Cellular phones Description The STB

Features

* Operating input voltage range from 2.4 V to 5.5 V
* ± 2% output voltage tolerance over process and temperature variations
* Bypass power save function
* Selectable output voltage with dedicated VSEL pin
* Very fast line and load transients
* 2.5 MHz

Applications

* where the output voltage is within the battery voltage range. The low-RDS(on) N-channel and P-channel MOSFET switches are integrated and help to achieve high efficiency. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage from either lower power consumption or b
