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