LM27403SQX/NOPB More Information

LM27403 Synchronous Buck Controller: OMO Electronic LM27403 synchronous buck controller offers exceptional levels of integration and performance for superior efficiency in high power density, point-of-load (POL) DC-DC regulator solutions. The resistor-programmable switching frequency from 200 kHz to 1.2 MHz and integrated, high-current MOSFET gate drivers with adaptive deadtime offer flexibility to optimize solution size and maximize conversion efficiency. High precision and low output voltage are easily obtained with a 0.6-V, 1% accurate voltage reference together with a 30-ns high-side MOSFET minimum controllable on-time. Using lossless inductor dc resistance (DCR) current sensing and an inexpensive 2N3904 BJT to sense temperature remotely at the inductor, the LM27403 supports accurate and thermally-compensated overcurrent protection (OCP). The LM27403 has a conventional voltage-mode control loop with high gain-bandwidth error amplifier and PWM input voltage feedforward to simplify compensation design and enable excellent transient response throughout the full line voltage and load current ranges. Forced-PWM (FPWM) operation eliminates frequency variation to minimize EMI in sensitive applications. An open-drain Power Good circuit provides power-rail sequencing and fault reporting. Other features include programmable system-level thermal shutdown with automatic recovery, output voltage remote sense, configurable soft-start, monotonic startup into prebiased loads, an integrated bias supply low-dropout (LDO) regulator, external power supply tracking, precision enable with customizable hysteresis for programmable line undervoltage lockout (UVLO), and synchronization capability for beat frequency sensitive and multiregulator applications. The LM27403 is offered in a 4-mm x 4-mm thermally-enhanced WQFN-24 package with 0.5-mm pitch.Learn More
