Product Information
Product Overview
LTC®3633 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 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. An internal phase lock loop servos the on-time of the internal one-shot timer to match the frequency of the internal clock or an applied external clock. Typical applications are distributed power systems, battery powered instruments, point of load power supplies.
- Operating frequency is programmable and synchronizable from 500KHz to 4MHz with an external resistor
- High frequency capability allows the use of small surface mount inductors and capacitors
- Up to 95% efficiency, low duty cycle operation is 5% at 2.25MHz
- Selectable 0°/180° phase shift between channels, power good status outputs
- Current mode operation for excellent line and load transient response
- 0.6V reference allows low output voltages
- Output voltage tracking and soft-start capability, short-circuit protected
- Overvoltage input and overtemperature protection, low power 2.5V linear regulator output
- 28-lead plastic QFN package
- Temperature rating range from –40°C to 125°C
