High Efficiency up to 95%
APW8805 is a 3A synchronous buck converter with inte-
Adjustable Output Voltage from 0.6V to VVIN
grated 75mΩ high side and 55mΩ low side power
Integrated 75mΩ High Side / 55mΩ Low Side MOSFETs. The APW8805, design with a current-mode
MOSFETs
control scheme, can convert wide input voltage of 2.6V to
Low Dropout Operation: 100% Duty Cycle Mode Selection
- APW8805 : PFM/PWM mode Stable with Low ESR Ceramic Capacitors Power-On-Reset Detection on VCC and VIN
6V to the output voltage adjustable from 0.6V to 6V to provide excellent output voltage regulation. The APW8805 is equipped with an automatic PFM/PWM mode operation. At light load , the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. At PWM mode, the switching
Integrated Soft-Start and Soft-Stop
frequency is set by the external res...
