Product Overview
LTC3633A-1 is a high efficiency, dual-channel monolithic synchronous buck regulator using a controlled on-time, current mode architecture, with phase lockable switching frequency. The two channels can run 180° out of phase to relax the requirements for input and output capacitance. The operating supply voltage range is from 3.6V to 20V, making it suitable for lithium-ion battery stacks as well as point of load power supply applications from a 12V or 5V supply. The operating frequency is programmable from 500kHz to 4MHz with an external resistor and may be synchronized to an external clock signal. The high frequency capability allows the use of small surface mount inductors and capacitors. Typical applications are distributed power systems, battery powered instruments, point of load power supplies.
- 3A output current per channel, up to 95% efficiency
- Output voltage tracking and soft-start capability, short-circuit protected
- Low duty cycle operation is 5% at 2.25MHz, adjustable switching frequency is 500kHz to 4MHz
- Selectable 0°/180° phase shift between channels, power good status outputs
- Output voltage range from 1.5 to 12V at VON = VOUT
- External frequency synchronization, 0.6V reference allows low output voltages
- Current mode operation for excellent line and load transient response
- User selectable burst mode® operation or forced continuous mode operation
- Overvoltage input and overtemperature protection
- 28-lead (4mm × 5mm) plastic QFN package, -40°C to 125°C temperature range
