KP52220XB
KP52220XB A 4.5V to 17V input, 2A output, 600kHz synchronous buck converter in a SOT23-6 package. The KP522201B/08B is a simple, easy-to-use, and highly integrated synchronous buck converter. It features a wide input voltage range of 4.5V to 17V, making it ideal for various common input voltage rails such as 12V and 15V. It supports a continuous output current of up to 2A with an output voltage range of 0.6V to 7V. The KP522201B operates in Pulse Frequency Modulation (PFM) mode under light load to maintain high light-load efficiency; the KP522208B operates in Forced Pulse Width Modulation (FPWM) mode to achieve a fixed switching frequency and low output ripple under full load current. The KP522201B/08B integrates comprehensive protection features, including Under Voltage Lockout (UVLO), Cycle-by-Cycle Current Limiting (OCL), Undervoltage Protection (UVP), Overvoltage Protection (OVP), and Over Temperature Protection (OTP), to ensure safe and reliable operation under various operating conditions. The KP522201B/08B is available in a small SOT23-6 package and operates over a junction temperature range of -40℃ to 125℃.
