摘要原文 In this paper, based on the small signal analysis of switching power converters under a hysteretic current mode control, a unified PWM switch model is derived. The model is easy to handle because all manipulations are performed on a circuit diagram which includes simply-described function...
the control circuitry arranged in the buck-boost mode: responsive to a current flowing through the inductor being lower than a predetermined low current threshold, to control the switches to couple the inductor between the input voltage and a common potential; responsive to the current flowing throu...

A new quasiconstant hysteretic current mode control is presented by introducing a switching frequency feedback to the normal hysteretic control. The merits of the new control approach are good stability and fast dynamic response. The switching frequency is stabilized within small range around the refer...
The 1.25-MHz single-inductor multiple-output (SIMO) converter presented here employs a buck stage to buck and boost 3.6 V to 0.8, 1.2, and 4.5 V and uses nested hysteretic current-mode control to respond within 1 μs to 20-mA load dumps across 0.8 and 1.2 V and 2 μs to 5-mA ...

The MP24894 is a high-efficiency step-down controller. It is designed to operate in continuous current mode (CCM) to power LEDs of high-brightness with a wide input voltage range of 6V to 60V. The MP24894 employs a hysteretic control architecture that a
We demonstrate a 90-240 MHz single phase converter with fast hysteretic control and output conversion range of 33%-80%. The converter achieves an efficiency of 80% at 180 MHz, a load response of 40 ns for a 120 mA current step and a peak-to-peak ripple less than 25 mV. The circuit...

A hysteretic mixed-signal controller for high-frequency switch-mode power supplies that achieves both very fast transient response and constant switching frequency under steady-state operation is presented. The mixed-signal controller combines three control loops: analog nonlinear current loop, digital line...
