IRU3037-8-pin synchronous PWM controller
The IRU3037 controller IC is designed to provide a low-cost on-board DC-to-DC synchronous buck regulator converter application. With today's ASIC migration product requirements, such as low supply voltages of 1.8V and low, coupled with currents exceeding 3A, the legacy is simply too lossy to use a linear regulator when the input supply is 5V, or even in some cases, with 3.3V input power supply. The IRU3037, together with dual N-channel MOSFETs such as the IRF7313, provides a low cost solution for such applications. The device features an internal 200KHz oscillator (400kHz "A" version), under-voltage lockout VCC and VC supplies, an external programmable soft-start function, as well as output under-voltage detection, lockout device output short-circuit detection.
