LMR62014XMF 开关 稳压器  20V out,1.4A

1FEATURES DESCRIPTION

23 The LMR62014 switching regulator is a current-mode • Input Voltage Range of 2.7V to 14V

boost converter operating at fixed frequency of

• Output Voltage up to 20V 1.6 MHz.

• Switch Current up to 1.4A

The use of SOT-23 package, made possible by the

• 1.6 MHz Switching Frequency minimal power loss of the internal 1.4A switch, and

• Low Shutdown Iq, <1 μA use of small inductors and capacitors result in the

industry's highest power density. The LMR62014 is • Cycle-by-Cycle Current Limiting

capable of greater than 90% duty cycle, making it

• Internally Compensated ideal for boosting to voltages up to 20V.

• 5-Pin SOT-23 Packaging (2.92 x 2.84 x 1.08mm)

These parts have a logic-level shutdown pin that can

• Fully Enabled for WEBENCH® Power Designer be used to reduce quiescent current and extend

battery life.

PERFORMANCE BENEFITS

Protection is provided through cycle-by-cycle current

• Extremely Easy to Use limiting and thermal shutdown. Internal compensation

• Tiny Overall Solution Reduces System Cost simplifies design and reduces component count.

APPLICATIONS
