DC-DC преобразователи интегральные MAX17502EATB+

Синхронный понижающий DC-DC преобразователь с ШИМ , 600кГц, 4.5В-60В (Vin), 3.3В/1A выход, TDFN-10

The MAX17502EATB+ is a 60V, 1A, high efficiency, synchronous step down DC to DC converter in 10 pin TDFN package. The high efficiency, high voltage and synchronous step down DC to DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range. The device features peak-current-mode control with pulse width modulation (PWM) and operates with fixed switching frequency at any load. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage level. An open-drain RESET pin provides a delayed power-good signal to the system upon achieving successful regulation of the output voltage.
