The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use. The device is optimized to work over the input voltage range of 2.95V to 5.5V making it suitable for a wide variety of low voltage systems. The device features internal over voltage protection (OVP) and over current p.
