Overview

LTC1433/LTC1434 450mA, Low Noise Current Mode Step-Down DC/DC Converters DESCRIPTION The LTC®1433/LTC1434 are monolithic pulse width modulated step-down DC/DC converters.
By utilizing current mode switching techniques, they provide excellent AC and DC load and line regulation.
Both devices operate at a fixed frequency with the LTC1434 phase-lockable to an external clock signal.
Both devices incorporate two internal P-channel power MOSFETs with a parallel combined resistance of 0.
6Ω (at a supply of 10V).
The Adaptive Power output stage selectively drives one or both of the switches at frequencies up to 700kHz to reduce switching losses and maintain high efficiencies at low output currents.
