NX7101 Datasheet | Microsemi

DESCRIPTION NX7101 is a 340k Hz fixed The controller is equipped with output frequency, current mode, PWM over-voltage protection which protects the synchronous buck (step-down) DC- IC under a open load condition. DC converter, capable of driving a 2A Additional safety features include under load with high efficiency, excellent voltage lock-out (UVLO), programmable line and load regulation. The device soft-start and over-temperature protection integrates N-channel power MOSFET (OTP) to protect the circuit. switches with low on-resistance. This IC is available in SOIC-8 Current mode control provides fast package. transient response and cycle-by-cycle current limit.
