Gamma Microelectronics GM7130

The GM7130 series of regulators provide all the active functions for a step-down (buck) switching regulator, and drive 3A load with excellent line and load regulation. These regulators are simple to use and require a minimum number of external components. The GM7130 series are highefficiency replacements for popular three-terminal linear regulators, requiring a smaller heatsink or even no heatsink.

APPLICATIONS

: Pre-regulator for linear regulators High-efficiency step-down buck regulator On-card/board switching regulators Positive to negative converter (buck-boost) TO-263 (S) 5-Lead Surface-Mount Package Top View 5 - ON/OFF 4 - Feedback 3 - Ground 2 - Output 1 - VIN w w .D w t a S a e h GM7130’s are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and a versatile Adjustable output version.

FEATURES

include internal frequency compensation and a fixedfrequency oscillator. The GM7130’s perform well with standard inductors from several manufacturers, simplifying the design of switch-mode power supplies. The GM7130 series guarantee ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, with 50 µA (typical) standby current. The output switch has cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. t e U 4 .c m o Connectio...
