Additional Information

Step-Down Switching Voltage Regulators
Military Qualified

The LT1076MK is a monolithic bipolar switching regulator. This device is rated at 2A and requires only a few external parts for operation. The power switch, all oscillator and control circuitry, and all current limit components, are included on the chip. This switching regulator can be used several different ways, such as a positive-to-negative converter, a negative boost converter, or a flyback converter.

Features:
- 100kHz Switching Frequency
- Greatly Improved Dynamic Behavior
- Only 8.5mA Quiescent Current
- Operates up to 45V Input
- Micropower Shutdown

Maximum Ratings
Input Voltage: 45V
Switch Voltage with Respect to Input Voltage: 64V
Switch Voltage with Respect to Ground Pin (VSW Neg): 35V
Feedback Pin Voltage: -2V, +10V
Shutdown Pin Voltage (Not to Exceed VIN): 40V
ILIM Pin Voltage(FOrced): 5.5V
Max. Operating Ambient Temperature Range: -55° to 125°C

Typical Electrical Characteristics
(over full operating temperature range unless otherwise noted):

Switch "On" Voltage (ISW = 0.5A): 1.2VC max.
Switch "Off" Leakage @ TJ = 25°C (VIN = 25V, VSW = 0): 150uA max.
Supply Current (40V < VIN < 60V): 9.0mA
Minimum Supply Voltage (Normal Mode): 7.3V
Switch Current Limit (ILIM Open): 2.6A
Switching Frequency Line Regulation (8V ≤ VIN ≤ VMAX): 0.03%/V
Feedback Pin Bias Current (VFB = VREF): 0.5uA
Multiplier Reference Voltage: 24V
Thermal Resistance Junction to Case: 4.0°C/W max.
