he ZCC2410 is a high efficiency, high power density, wide input range, current mode boost converter. This converter integrates a 10mΩ, 24V power switch and a synchronous gate driver for high converter efficiency. It provides programmable switch peak current limit with an external resistor. The switching frequency in the PWM mode is adjustable ranging from 100 kHz to 1 MHz by an external resistor. An external compensation pin gives the user flexibility in setting loop dynamics and obtaining the optimal transient performance at all conditions. • • • • • • • 3V to 22V Wide Operation Voltage Range SDR Driver for Synchronous Solution External Compensation for high flexibility Integrated 10mΩ, 24V Power MOSFET Programmable Soft-start Time Programmable Switch Peak Current limit Programmable Switching 100 kHz to 1 MHz Frequency: • Programmable Input UVLO and UVLO Hysteresis Low Shutdown Current < 1µA Output Overvoltage Protection Thermal Shutdown at 150°C Available in 3x4mm QFN Package • • • • The ZCC2410 also includes input under-voltage lockout, output overvoltage protection, cycle-by- cycle overcurrent protection and thermal shutdown to prevent damage in the event of output overload.
