FEATURES
s s DESCRIPTIO s s s s s s s s s s U APPLICATIO S s s s Dual Regulated Outputs: One Switching Regulator and One Linear Regulator Excellent DC Accuracy: ±1.5% for Switcher and ±2% for Linear Regulator External N-Channel MOSFET Architecture No External Current Sense Resistor Required Burst Mode® Operation at Light Load (LTC1704) Continuous Switching at Light Load (LTC1704B) Linear Regulator with Programmable Current Limit Linear Regulator with Programmable Start-Up Delay Low Shutdown Current: <150µA High Efficiency Over Wide Load Current Range PGOOD Flag Monitors Both Outputs Small 16-Pin Narrow SSOP Package The LTC®1704/LTC1704B include a high power synchronous switching regulator controller plus a linear regulator controller. The switching regulator controller is designed to drive a pair of N-channel MOSFETs in a voltage mode, synchronous buck configuration to provide the main supply. The constant frequency, true PWM architecture switches at 550kHz, minimizing external component size, cost and optimizing load transient performance.
