Product Overview
LTC1435 is a synchronous step-down switching regulator controller that drives external N-channel power MOSFETs using a fixed frequency architecture. Burst ModeTM operation provides high efficiency at low load currents. A maximum duty cycle limit of 99% provides low dropout operation which extends operating time in battery-operated systems. The operating frequency is set by an external capacitor allowing maximum flexibility in optimizing efficiency. A secondary winding feedback control pin, SFB, guarantees regulation regardless of load on the main output by forcing continuous operation. Burst Mode operation is inhibited when the SFB pin is pulled low which reduces noise and RF interference. Soft start is provided by an external capacitor which can be used to properly sequence supplies. It is used in application such as notebook and palmtop computers, PDAs, cellular telephones and wireless modems, portable Instruments, battery-operated devices, DC power distribution systems etc.
- Wide VIN range is 3.5V to 36V

- Output voltages from 1.19V to 9V
- Logic controlled micropower shutdown is 25µA maximum
- Oscillator frequency is 125KHz typical at (COSC = 100pF)
- Operating ambient temperature is 0°C to 70°C
- Package style is 16-lead NSOIC
