The CXSD6169 is a buck switching regulator for wide operating voltage application fields. The CXSD6169 includes a high current P-MOSFET, high precision reference (0.5V) for comparing output voltage with a feedback amplifier, an internal dead-time controller and oscillator for controlling the maximum duty cycle and PWM frequency. It also has power-on programmable soft start time, short circuit PMOS turn-off and auto re-start protection functions.
˙Precision Feedback Reference Voltage: 0.5V (2%)
˙Wide Supply Voltage Operating Range: 3.6 to 20V
˙Low Current Consumption: 3mA
˙Internal Fixed Oscillator Frequency: 340KHz (Typ.)
˙Internal Soft-Start Function (SS)
˙Short Circuit Shutdown and Auto Re-start function (ARSCP)
˙Built-in P-MOSFET for 2A Loading Capability
˙Over Current Protection
˙Package: SOP-8L
