STEVAL-ISA052V2 Evaluation board for the PM6675AS high efficiency step-down controller with embedded 2 A LDO regulator Data Brief Features 4.5 V to 36 V input voltage range 0.6 V, 1% voltage reference 1.5 V fixed output voltage 0.6 V to 3.3 V adjustable output voltage 1.237 V 1% reference voltage available Very fast load transient response using constant on-time (COT) control loop No RSENSE current sensing using R of DS(ON) the low-side MOSFETs Negative current limit STEVAL-ISA052V2 Latched OVP, UVP and thermal shutdown Fixed 3 ms soft-start and source up to 2 Apk. Two fixed current limits (1 A and 2 A) can be chosen. Selectable pulse-skipping at light load An active soft-end is independently performed on Selectable no-audible (33 kHz) pulse-skip both the switching and the linear regulator outputs mode when disabled. All ceramic output capacitors application supported Output voltage ripple compensation Output soft-end Description This evaluation board is based on the PM6675AS device, which consists of a single high efficiency step-down controller and an independent low- dropout (LDO) linear regulator. The constant on-time (COT) architecture assures fast transient response supporting both electrolytic and ceramic output capacitors. An embedded integrator control loop compensates the DC voltage error due to the output ripple. Selectable low-consumption mode allows the highest efficiency over a wide range of load conditions. The low-noise mode sets the minimum switching frequency to 33 kHz for audio-sensitive applications. The LDO linear regulator can sink May 2008 Rev 1 1/4 For further information contact your local STMicroelectronics sales office. www.st.com 4Circuit schematic STEVAL-ISA052V2 1 Circuit schematic Figure 1.
