Product Description
Product Details
Description
The ST1S30 is a step-down DC-DC converter optimized for powering low output voltage applications. It supplies a current in excess of 3 A over an input voltage range from 2.7 V to 6 V.A high PWM switching frequency (1.5 MHz) allows the use of tiny surface-mount components.
Features
■ 1.5 MHz fixed frequency PWM with current control mode■ 3 A output current capability
■ Typical efficiency: > 90%
■ 2 % DC output voltage tolerance
■ Two versions available: power good or inhibit
■ Integrated output over-voltage protection
■ Non switching quiescent current: (typ) 1.5 mA over temperature range
■ RDSon (typ) 100 mΩ
■ Utilizes tiny capacitors and inductors
■ Operating junction temp. -25 °C to 125 °C
■ Available in DFN8 (4 x 4 mm) exposed pad
