降压/升压开关模式稳压器 BUCK/BOOST SWITCH-MODE REGULATOR

The is a buck/boost Switch-mode Regulator with integrated switches for voltage-mode control. With the aid of external components LC combination, the device regulates the output to 5V ±3% for a wide input-voltage range. It offers a reset function to detect and indicate when the 5V output rail is outside of the specified tolerance. This reset delay is programmable using an external timing capacitor on the REST terminal. Additionally, an alarm AOUT feature is activated when the input supply rail Vdriver is below a prescaled specified value set by the AIN terminal. It has a frequency-modulation scheme to minimize EMI. The clock modulator permits a modulation of the switching frequency to reduce interference energy in the frequency band. The 5Vg output is a switched 5V regulated output with internal current limiting to prevent assertion of reset when powering a capacitive load on the supply line. This function is controlled by the 5Vg_ENABLE terminal.
