OC58650 is a switching step-down DC-DC that supports a wide input voltage up to 100V. OC58650 features low standby power consumption, high efficiency, low ripple, and excellent bus voltage regulation and load regulation. Support high current output, output current up to 2A or more.
OC58650 The output constant voltage value can be set by setting the voltage divider resistor on the FB pin.
OC58650 with fixed-frequency PWM control, the typical switching frequency is 150KHz. When the load is light, it will enter the skip cycle mode for high conversion efficiency.
OC58650 integrates soft-start and over-temperature protection circuits, output short-circuit protection, current limit protection and other functions to improve system reliability.
