The LTC® 1149 series is a family of synchronous stepdown switching regulator controllers featuring automatic Burst ModeTM operation to maintain high efficiencies at low output currents. These devices drive external complementary power MOSFETs at switching frequencies up to 250kHz using a constant off-time current-mode architecture.
Special onboard regulation and level-shift circuitry allow operation at input voltages from dropout to 48V (60V absolute max). The constant off-time architecture maintains constant ripple current in the inductor, easing the design of wide input range converters. Current mode operation provides excellent line and load transient response. The operating current level is user-programmable via an external current sense resistor.
The LTC1149 series incorporates automatic power saving Burst Modeoperation when load currents drop below the level required for continuous operation. Standby power is reduced to only about 8mW at VIN = 12V. In shutdown, both MOSFETs are turned off.
