说明
- Typical Application Circuit for LTC1143 Dual 1.8V/3A and 2.5V/2A with Burst Mode Defeated. The LTC1143 series is a dual step-down switching regulator controller featuring automatic Burst Modem operation to maintain high efficiencies at low output currents. This device is composed of two separate regulator blocks, each driving an external power MOSFET at switching frequencies up to 400kHz using a constant off-time current mode architecture
