High Voltage, 3A, 200kHz/100kHz Step-Down Switching Regulators

DESCRIPTION\nThe LT®3430/LT3430-1 are monolithic buck switching regulators that accept input voltages up to 60V. A high ef fi ciency 3A, 0.1Ω switch is included on the die along with all the necessary oscillator, control and logic circuitry. A current mode architecture provides fast transient respon ■ Wide Input Range: 5.5V to 60V\n■ 3A Peak Switch Current over All Duty Cycles\n■ Constant Switching Frequency:\n   200kHz (LT3430)\n   100kHz (LT3430-1)\n■ 0.1Ω Switch Resistance\n■ Current Mode\n■ Effective Supply Current: 2.5mA\n■ Shutdown Current: 30µA\n■ 1.2V Feedback Reference Voltage\n■ Easil;
