LA8506

General Description LA8506 500KHz, 3A/40V Step-Down DC-DC Converter Features LA8506 is a current mode, step-down DC-DC converter that is designed to meet 3A output current, and utilizes PWM control scheme that switches with 500KHz fixed frequency. The input voltage range of LA8506 is from 8V to 40V, and available in adjustable output voltage from 1.222V to 24V. The supply current is only 1mA during operation and under 30uA in shutdown. This device provides an enable function that can be controlled by external logic signal. It also provides excellent regulation during line or load transient. Other features of soft-start current limit, thermal shutdown protection, and short circuit protection are also included. Due to the low RDS(ON) of the internal power MOSFET, this device provides high efficiency step-down applications. The package is available in standard ESOP-8. l Adjustable Output from 1.222V to 24V l 8V to 40V Input Voltage Range l Continuous 3A Output Capability l 500KHz Oscil...
