Product Overview
LTC3633 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, which relaxes the requirements for input and output capacitance. The operating supply voltage range is from 3.6V to 15V, making it suitable for dual cell lithium-ion batteries as well as point of load power supply applications from a 12V or 5V supply. The operating frequency is programmable and synchronizable from 500KHz to 4MHz with an external resistor. The high frequency capability allows the use of small surface mount inductors and capacitors. The unique constant frequency/controlled on-time architecture is ideal for high step-down ratio applications that operate at high frequency while demanding fast transient response. It is used in application such as distributed power systems, battery powered instruments, point of load power supplies etc.
- 3A output current per channel, upto 95% efficiency
- Current mode operation for excellent line and load transient response
- 0.6V reference allows low output voltages
- User selectable Burst Mode® operation or forced continuous operation
- Output voltage tracking and soft-start capability
- Short-circuit protected, external frequency synchronization
- Overvoltage input and overtemperature protection, low power 2.5V linear regulator output
- Power good status outputs, oscillator frequency is 2MHz typical
- Shutdown current is 13µA typical at (RUN1 = RUN2 = 0V)
- Operating temperature is -40°C to 125°C, package style is 28-lead plastic TSSOP
