Описание L4970A
The L4970A is a Step-down Monolithic Power Switching Regulator IC delivering 10A at a voltage variable from 5.1 to 40V. This device uses a DMOS output transistor to obtain very high efficiency and very fast switching times. Features of this include reset and power fail for microprocessors, feed forward line regulation, soft start, limiting current and thermal protection. The device is mounted in a 15-lead multi-watt plastic power package and requires few external components. Efficient operation at switching frequencies up to 500kHz allows reduction in the size and cost of external filter components.
• 0 to 90% Duty cycle range
• Internal feed-forward line regulation
• Internal current limiting
• Precise 5.1V ±2% on-chip reference
• Reset and power fail functions
• Input/output sync pin
• Under voltage lock out with hysteretic turn-on
• PWM latch for single pulse per period
• Very high efficiency
• Continuous mode operation
