Synchronous Buck Converter Controller

FEATURES 6- to 16.5-V Input Range (Si9150CY) Voltage-Mode PWM Control Low-Current Standby Mode Enable Control Dual 100-mA Output Drivers 2% Band Gap Reference Multiple Converters Easily Synchronized Over-Current Protection
DESCRIPTION
The Si9150 synchronous buck regulator controller is ideally
suited for high-efficiency step down converters inbattery-powered equipment. Combined with the Si9943DY
MOSFET half-bridge, a 90% efficient, 7.5-W, 3.3-V or 5-Vpower supply can be implemented using standard surface-mount assembly techniques. The wide input range allows
operation from NiCd or NiMH battery packs using six to tencells.
Over-current protection is achieved by sensing the on-state
voltage drop across the high side p-channel MOSFET, whicheliminates the need for a current sense resistor.
Duty ratios of 0 to 100% and switching frequencies up to 300
kHz are possible. The IC can be disabled by pulling EN low(IDD = 100 �A), or the 2.5-V reference can be maintained, with
all other functions disabled, by pulling STBY low (IDD =500 �A).
The Si9150 is available in both standard and lead (Pb)-free14-pin SOIC and rated for the commercial temperature range
of 0 to 70�C (C suffix), and the industrial temperature range of−40 to +85�C (D suffix).
