EV8862-Q-00A 2.8 - 22V V , 2A I , 4-Switch, IN OUT Integrated Buck-Boost Converter 2 with I C Interface DESCRIPTION FEATURES The EV8862-Q-00A is an evaluation board for Wide 2.8V to 22V Operating Input Voltage MP8862, which is a synchronous, 4-switch, Range integrated buck-boost converter capable of (1) 1V to 20.47V Output Voltage Range (5V regulating the output voltage from a 2.8V to 22V 2 Default) with 10mV Resolution through I C wide input voltage range with high efficiency. 2A Output Current or 4A Input Current The integrated output voltage scaling and Four Low R Internal Buck Power DS(ON) adjustable output current limit functions meet MOSFETs the USB power delivery (PD) requirement. Adjustable Accurate CC Output Current 2 The MP8862 uses constant-on-time (COT) Limit with Internal Sensing MOSFET via I C control in buck mode and constant-off-time 500kHz Switching Frequency control in boost mode, providing fast load Output Over-Voltage Protection (OVP) transient response and smooth buck-boost Hiccup mode transient. The MP8862 provides auto Output Short-Circuit Protection (SCP) with PFM/PWM or forced PWM switching modes, Hiccup programmable output constant current (CC) Over-Temperature Warning and Shutdown current limit, which supports flexible design for 2 I C Interface with ALT Pin different applications. 2 Four Programmable I C Addresses Full protection features include over-current One-Time Programmable (OTP) Non- Volatile Memory protection (OCP), over-voltage protection 2 (OVP), under-voltage protection (UVP), I C Programmable Line Drop Compensation, programmable soft start, and thermal shutdown. PFM/PWM Mode, Soft Start, OCP, etc. EN Shutdown Discharge Programmable The MP8862 is available in a 16-pin QFN Available in a QFN-16 (3mmx3mm) (3mmx3mm) package.
